In the present embodiment, the music database 10 corresponds to the music data storage unit, the music list generation unit corresponds to a part of the function of the control unit 40, and the music data processing unit corresponds to a part of the function of the control unit 40, playback. Corresponding to the unit 80 and the reproduction control unit 85.

  In this embodiment, the control unit 40, the reproduction unit 80, and the reproduction control unit 85 are shown as separate blocks. However, they are not necessarily different from each other, and are not necessarily separate pairs, such as an integrated circuit such as an LSI or a dedicated signal. A single chip using a processing circuit may be used. In addition, each of the functions corresponding to these blocks may be formed as a chip. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration. Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI, or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used. Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology.

  FIG. 2 is an example of the composition of music data stored in the music database 10. In the music database 10, a music number, music data, related information, and impression information are stored for each music. The song number is a unique number set for each song to identify the song. The music data is data representing the music signal of the music, and includes, for example, waveform data of the music by linear PCM and a compressed data format such as AAC. The related information includes, for example, information related to music such as a song name, artist name, album title, songwriter, composer, arranger, genre, performance time, and the like. Impression information is information about the listener's impression when listening to music. Here, the impression information includes information such as the degree of preference and impression of the music, and can be changed by the user. The music data stored in the music database 10 can be added or deleted as appropriate. When a song is added, a song number is automatically assigned to the song.

  The degree of preference for music refers to the degree of preference for music and is set for each music. The degree of preference of music may be set by executing a file operation on the music, or may be determined according to a generation rule described later. Further, the degree of preference of music may be expressed by numerical values, and likes / dislikes may be expressed by binary values. The impression of music is information set to classify music according to the impression received by the listener. For example, it is expressed by whether or not each song corresponds to an item indicating an impression such as “bright song” or “sad song”. The impression of the music may be set by the user or determined according to the generation rule. Furthermore, for the impression of music, new items such as “favorite 1”, “favorite 2”, “for sleeping”, and “for alarm clock” may be added or deleted by the user.

  The input receiving unit 70 receives various instruction inputs from the user. The input receiving unit 70 includes buttons, a touch panel, and the like, and is displayed on the display unit 60. The input receiving unit 70 includes a selection button, a file operation button, and a playback button for list creation mode and generation rule setting mode, which will be described later.

  The control unit 40 performs various control processes according to user instructions received by the input receiving unit 70. The control unit 40 can receive signals from the input receiving unit 70, the generation rule storage unit 50, and the history information storage unit 30. The control unit 40 can control the display unit 60, the music database 10, and the playlist storage unit 20 based on signals from the input receiving unit 70.

  The history information storage unit 30 stores history information. Here, the history information is a history of operation contents input to the music operation input unit 90 during music reproduction. FIG. 3 shows an example of history information stored in the history information storage unit 30. As shown in FIG. 3, the history information includes a song number, a song operation time, a song operation content, and a file operation name for each song. The song number is a unique number set for each song for identifying the song. The music operation time is the time when an operation is input to the music operation input unit 90. The music operation content is the content of the operation input to the music operation input unit 90. For example, the content of the operation includes various operations such as reproduction, stop, pause, cueing, volume change, skip, and the like. Hereinafter, an operation input to the music operation input unit 90 by the user and performed on the music is referred to as a music operation. Of the music operations, an operation for playing a music is called a playback operation. The operations performed on the music include operations such as deleting the music from the music database 10, changing the preference setting of the music, and changing the setting of the music impression. Hereinafter, operations other than music operation including change of music impression information and music deletion are referred to as file operations. The file operation name stored as history information is the name of the file operation actually performed on the music. For example, in FIG. 3, for a music piece whose music number is “231”, a file operation in which the preference is set to “4” is performed after the operation indicated by the music operation content is performed during playback. Yes. Note that the music list generated by the music list generating apparatus 1 according to the present embodiment is described as a music list because it can be used not only for reproduction but also for file operations.

  The reproduction list storage unit 20 stores a list of music data to be reproduced using the music data stored in the music database 10 in accordance with the music list generated by the control unit 40.

  The generation rule storage unit 50 stores the generation rule created by the control unit 40. FIG. 4 shows an example of generation rule data. The generation rule includes a registration generation rule and an extraction generation rule. Further, each generation rule includes a generation rule name and a reproduction operation condition. The reproduction operation condition includes a time condition and a content condition corresponding to the generation rule name. Here, the generation rule is a rule for generating a music list. Specifically, the generation rule is that a specific music operation is performed based on the correspondence between the music operation performed during playback of a certain music and the file operation performed after the music operation on the music. This is used to select a music from the music database 10 as a music to be subjected to a predetermined file operation and generate a music list. For example, in FIG. 4, the generation rule with the generation rule name “delete from DB” is used when the user deletes music data from the music database. In other words, when this generation rule is specified by the user, the music list generation device selects a music for which “pause” and “skip” operations have been performed during music playback from the music database 10, and the music database A list of songs to be deleted is generated from 10. The registration generation rule is a generation rule registered in advance or a generation rule registered by the user. On the other hand, the extraction generation rule is a rule that is automatically generated by learning the relationship between a specific file operation and a music operation based on the history information stored in the history information storage unit 30. Generation rule registration and update processing will be described later.

  The display unit 60 is configured by a display device such as a CRT or a liquid crystal display device. The display unit 60 receives an instruction from the control unit 40, an input screen for setting conditions for creating a music list, setting a registration generation rule, an input receiving unit 70 for receiving instructions from the user, and the like. Is displayed.

  The music operation input unit 90 receives instruction inputs related to various music operations by the user. FIG. 5 is a diagram illustrating an example of the configuration of the music operation input unit 90. The music operation input unit 90 includes “play / pause” 90-4, “stop” 90-5, “skip” 90-6, “cue” 90-7, and “volume low” 90-1. In addition, each of the operation buttons “volume up” 90-2 and “end” 90-7 is received, and an instruction input by the user is accepted. In FIG. 5, six types of operation buttons are used, but the present invention is not limited to this. The operation buttons included in the music operation input unit 90 may be part of the six types.

  The playback control unit 85 controls the playback unit 80 in accordance with an input signal from the music operation input unit 90. Further, the reproduction control unit 85 stores the operation content input to the music operation input unit 90 during reproduction of the music in the history information storage unit 30 for each music. The reproduction unit 80 reproduces music based on the reproduction list stored in the reproduction list storage unit 20 in accordance with an instruction from the reproduction control unit 85.

  Next, the operation of the music list generation device according to the present embodiment will be described. FIG. 6 is a flowchart showing the flow of processing of the music list generation device. The process shown in FIG. 6 is started, for example, when the music list generating device 2 is turned on.

  First, in step S1, the control unit 40 determines a signal from the input receiving unit 70, and executes either the list creation mode or the generation rule setting mode. FIG. 7 shows an input receiving unit 70 for selecting a mode displayed on the display unit 60. The input receiving unit 70 is provided with a list creation button 71 and a generation rule setting button 72. Note that the input receiving unit 70 shown in FIG. 7 represents only buttons necessary for mode selection. The user can select a mode by pressing any button. When the list creation mode is selected, the control unit 40 executes the process of step S2. On the other hand, when the generation rule setting mode is selected, the process of step S12 is executed.

  Next, a process (step S2) when the list creation mode is selected in step S1 will be described. In step S2, the control unit 40 creates a music list. The control unit 40 performs a music operation after step S4 or a file operation after step S9 for each music in the music list.

  When determining that the list creation mode is selected in step S <b> 1, the control unit 40 displays the selection list creation screen 61 on the display unit 60. The selection list creation screen 61 is an input display screen related to setting conditions for creating a music list. FIG. 8 is a diagram illustrating an example of the input display screen. The input display screen is mainly configured by a selection condition input unit 21, an extraction list display unit 22, and a selection list display unit 23. Furthermore, the selection condition input unit 21 includes a related information condition input unit 24, a preference condition input unit 25, an impression condition input unit 26, a music operation condition input unit 27, and a music list selection unit 28. In the extraction list display unit 22, music that matches the conditions input to the selection condition input unit 21 among the music stored in the music database 10 is displayed, and a music list is created. FIG. 9 shows an example of the composition of the music list. In FIG. 9, in the music list, the list number and the music number of each music are registered. In addition, although the music displayed on the extraction list display part 22 was made into the music list in FIG. 8, it is not restricted to this. Of the music displayed on the extraction list display unit 22, the music arbitrarily selected by the user may be displayed on the selection list display unit 23, and these may be used as the music list. The contents displayed on the extraction list display unit 22 and the selection list display unit 23 are related information stored in the music database 10 and a part of impression information for the music of the music number registered in the music list. May be displayed.

  Next, condition input by the selection condition input unit 21 will be described. Each condition can be specified by the user. In the related information condition input unit 24, a specific music title, artist name, or the like can be input as a condition. In the preference level condition input unit 25, it is possible to input a condition such as a specific preference level or “preference level 4 or higher”. In the impression condition input unit 26, for example, it is possible to input a condition specifying an impression value or a value range.

  The music operation condition input unit 27 can set music operation conditions input to the music operation input unit 90. As described above, the content of the music operation input to the music operation input unit 90 is stored as history information in the history information storage unit 30 for each song. The control unit 40 searches and extracts music that matches the conditions from the history information stored in the history information storage unit 30. FIG. 10 is an example of an input screen displayed on the music operation condition input unit 27 of FIG. The music operation condition input unit 27 includes a time condition input unit 27-1 and a content condition input unit 27-2. Here, the content condition indicates a condition in which executed music operations including “play” and “pause” are arranged in time series. At this time, only one music operation may be performed. On the other hand, the time condition is a condition related to the execution time of the music operation specified by the content condition. The control unit 40 can calculate the execution time of the music operation from the time when the music operation stored in the history information storage unit 30 is performed, and can extract the music that matches the time condition. For example, as illustrated in FIG. 10, when the time condition is “within 2 seconds” and the content condition is “pause → skip”, the control unit 40 stores the reproduction operation condition in the history information storage unit 30. From the recorded history information, within 2 seconds, a music piece for which a skip operation has been input is searched after being paused during playback. In the present embodiment, the time condition can be set to “none”. The search results in this case are all the songs stored in the song database 10.

  In FIG. 8, the music list selection unit 28 can select a music list created based on the registration generation rule or the extraction generation rule. As described above, the generation rule selects, from the music database 10, a music for which a specific music operation has been performed as a music to be subjected to a predetermined file operation based on the correspondence between the music operation performed during playback and the file operation. Thus, it is used to generate a music list. FIG. 11 shows an example of an input screen displayed on the music list selection unit 28 of FIG. The music list selection unit 28 includes item buttons such as “delete from DB”, “preference level = 1”, and “bright music” for each of the registration generation rule and the extraction generation rule. When each item button is pressed, the control unit 40 displays on the extraction list display unit 22 a music list created by the process of step S13 described later.

  The selection condition input unit 21 can set a plurality of conditions in each of the condition input units 24 to 28, and can search these conditions by “AND”, “OR”, or the like. For example, in the case of extracting music pieces with a “preference level of 3 or more”, the search is performed with “OR” so that the results of “preference level 3”, “preference level 4”, and “preference level 5” apply to any of the conditions. May be. In addition, the related information condition input unit 24 may search for two conditions of “specific artist” and “preference degree 3 or more” by “AND”.

  In this way, a list of songs selected on the condition of the related information, impression information, and history information of the song is created by the process of step S2, and the process of the next step S3 is performed.

  In the subsequent processing of step S3, it is determined whether to perform reproduction or file operation for each song in the song list. The reproduction operation reproduces each song in the song list. On the other hand, the file operation performs various processes including deletion from the music database 10 and changing preference settings and impression settings for the music in the music list. Here, the execution instruction content is selected by the user via the input receiving unit 70. FIG. 12 is a diagram illustrating an example of the configuration of the input receiving unit 70 displayed on the display unit 60. The input receiving unit 70 includes a playback command button 70-1 and file operation buttons 70-2 to 70-4. Note that the input receiving unit 70 shown in FIG. 12 shows only buttons for selecting execution command contents. When the control unit 40 determines that the playback command button has been pressed by the user, the control unit 40 executes the process of step S4 in order to play back each piece of music included in the music list. On the other hand, if it is determined that a command button other than the playback command button has been pressed, the process of step S9 is executed to perform the file operation.

  First, processing (steps S4 to S8) when the playback command button is pressed in step S3 will be described. In step S4, the control unit 40 creates a reproduction list for reproducing each piece of music in the music list. Here, the reproduction list further includes music data of each song in the song list in addition to the list number and the song number. FIG. 13 is a diagram illustrating an example of the configuration of a reproduction list. The reproduction list includes a list number, a music number, and music data. The control unit 40 acquires corresponding music data from the music database 10 from the list number and the music number of each music in the music list, and creates a reproduction list. The created playlist is stored in the playlist storage unit 20.

  In the subsequent step S5, a music reproduction operation is accepted. The music operation including the reproduction operation is performed according to a signal input to the music operation input unit 90. When the reproduction control unit 85 determines that the reproduction button 90-4 of the music operation input unit 90 has been input, the reproduction control unit 85 instructs the reproduction unit 80 to reproduce the music. In response to the instruction from the reproduction control unit 85, the reproduction unit 80 reproduces each piece of music in the reproduction list created in step S4 in the designated order.

  Furthermore, in the process of step S6, a music operation for the music being reproduced is accepted. In the music operation input unit 90 shown in FIG. 5, when an operation button is pressed by the user, a signal related to each operation is sent to the reproduction control unit 85. For example, if “high volume” 90-1 is selected during music playback, the volume is increased. If “Skip” 90-6 is selected during the reproduction of a music piece, the reproduction of the currently reproduced music piece is stopped, and the next music piece in the music list is reproduced.

  Next, in step S7, the reproduction control unit 85 determines whether or not the end button 90-7 has been selected. If it is determined that the end button has been selected, the playback control unit 85 ends the music playback process and executes the process of step S11. On the other hand, if it is determined that an operation button other than the end button has been selected, the process of step S8 is performed. Note that the determination as to whether or not the reproduction of the music has ended is not limited to the case where the end button is selected in step S6. For example, not only the music operation input unit 90 but also a button having the same function as the end button may be provided in the input receiving unit 70.

  In the process of step S8, the reproduction control unit 85 stores the operation content input to the music operation input unit 90 in step S6 in the history information storage unit 30 as a music operation history, and updates the history information. As shown in FIG. 3, the music operation history information includes an operation input to the music operation input unit 90 and a time when the operation is input. The reproduction control unit 85 records the music number, the reproduction operation time, the music operation content, and the file operation name as history information. For example, when the “play / pause” button 41-4 is pressed during music playback, the playback control unit 85 records “pause” of the operation content and the time when the button is pressed. . Further, when the “play / pause” button 41-4 is pressed while the playback of the music is stopped, “play” of the operation content and the time when the operation button is pressed are recorded. When the reproduction control unit 85 finishes updating the history information, the reproduction control unit 85 returns to step S5 again and accepts the input of the music operation. Thus, the process when the reproduction command is selected in step S3 ends.

  Next, processing (steps S9 and S10) when it is determined in step S3 that the file operation has been executed will be described. The process of step S9 is performed when a command button other than the playback command is selected in step S3. That is, the control unit 40 performs file operations corresponding to the items selected by the user in the input receiving unit 70 shown in FIG. FIG. 14 shows an example of the contents of the file operation. Each file operation is associated with the file operation name and the operation content performed on the music. For example, when “preference level = 1” of the input receiving unit 70 in FIG. 12 is selected, the control unit 40 sets the preference level of each song in the song list to 1. Similarly, when “delete from DB” is selected, each song in the selection list is deleted from the song database 10. In this way, processing other than reproduction can be performed on the created music list by the processing in step S9.

  Through the subsequent processing in step S10, the contents of the file operation executed in step S9 are stored in the history information storage unit 30 as history information. The control unit 40 searches the history information for the same music as the music on which the file operation was performed. Then, the file operation name is updated in the history information of the corresponding music. At this time, the file operation name may be newly overwritten by deleting the previously stored file operation name, or may be added to a plurality of items. Further, when the same music as the music on which the file operation has been performed does not exist in the history information, a separate file operation history storage unit may be provided and stored in the storage unit. In this case, the update operation of the music operation history information in step S8 refers to the file operation history storage unit, searches for the same music as the music being reproduced, and sets the file operation name as the file operation in the history information storage unit 30. This is done by adding to the name column. This makes it possible to clarify the correspondence between the history of the file operation and the music operation even for the music that has been file-operated in the past, and to update the extraction generation rule described later more accurately. As described above, when the file operation history information is updated, the process of the next step S11 is performed.

  Next, in the process of step S11, the extraction generation rule is updated. As shown in FIG. 4, the generation rule storage unit 50 stores registration generation rules and extraction generation rule data. Among these, the extraction generation rule is updated by the process of step S10. On the other hand, the registration generation rule is updated by the process of step S12.

  The extraction generation rule is generated by learning the relationship between a specific file operation and a music operation based on the history information. That is, the control unit 40 finds the most frequently used combination (generation rule) from the combination of music operation and file operation from the history information stored in the history information storage unit 30. At this time, the generation rule checks the combination of the content of the music operation (for example, “playback” or “cue”) and the time of the music operation (for example, “within 1 second” or “within 10 seconds”) as a brute force Is done. For example, when it is found from the history information that the music that was skipped after being paused within 1 second during the playback of the music has the highest frequency of file operations that are subsequently deleted from the music database, The extracted generation rules are the time condition “within 1 second”, the content condition “skip after being paused”, and the generation rule name “delete from DB”.

  Thus, the process of step S11 finds a certain rule that is predicted to execute a predetermined file operation. By using this generation rule, the user can easily create a list of music to be operated on.

  In the process of step S11, the contents of the music operation may be stored together. For example, a music operation for increasing the volume and a music operation for decreasing the volume may be stored as one music operation including “volume adjustment”. Thereby, a flexible extraction generation rule can be created. In addition, the extraction generation rule may be generated from the most frequently used combination of music operations and file operations, or may be generated by setting a plurality of music operation conditions.

  On the other hand, in the process of step S12, the registration generation rule is updated by the user. In step S1, the control unit 40 determines that the generation rule setting button 12 of the input receiving unit 70 shown in FIG. 7 has been selected, and displays an update screen for updating the registration generation rule on the display unit 60. Let FIG. 15 is a registration generation rule update screen 55 displayed on the display unit 60. The registration generation rule update screen 55 is mainly configured of a generation rule name 55-1, a time condition input unit 55-2, a content condition input unit 55-3, and a change determination unit 55-4. The user can set a time condition and a content condition corresponding to the generation rule name. When the control unit 40 determines that the condition is input by the user and the change determination unit 51-4 is pressed, each condition of the corresponding registration generation rule among the registration generation rules stored in the generation rule storage unit 50 is determined. To change. FIG. 16 shows an example of the music operation condition of the registration generation rule. Hereinafter, specific examples of the music operation conditions of the registration generation rule will be shown.

  For example, the registration generation rule may associate an input operation combining “pause” and “skip” with a file operation “delete from music database”. Thereby, the control unit 40 selects the music for which the above input operation has been performed as the music to be deleted from the music database 10. Thus, the user's “intention to delete the music” can be confirmed by using the combined operation of pause and skip as the music operation condition. Therefore, the user can set the music to be deleted from the music database by inputting the operation.

  Further, for example, the registration generation rule may associate an input operation of the “volume adjustment button” with a file operation of “setting preference”. That is, an operation for increasing / decreasing the volume adjustment button may be associated with a file operation for setting a preference level. Specifically, as shown in FIG. 16, when the direction of increasing the volume control button is “+” and the direction of decrease is “−”, the volume control button “+” is input twice during playback. The music for which “-” is input twice immediately after that is set to “preference level 5”. The music to which the volume adjustment buttons “+, −” are input is set to “preference level 4”. The music to which the volume adjustment buttons “+, −, −, +” are input is set to “preference level 3”. The music to which the volume control buttons “−, +” are input is set to “preference level 2”. Further, the music to which the volume adjustment buttons “−, −, +, +” are input is set to “preference level 1”. In this manner, the user can set the preference level while keeping the volume being played back by inputting the above operation on the volume adjustment button.

  Further, for example, the registration generation rule may associate an input operation combining “pause”, “volume control button”, and “play” with a file operation for “setting the impression of music”. Specifically, during playback of a music piece, the music input with “pause, volume-, play” of the music operation input unit 90 is set as an impression as “fun music”. Also, an impression is set as a “sad song” for a song for which “pause, volume-, volume-, playback” is input. A plurality of patterns are registered in advance for the relationship between the impression of the music and the input operation. The pattern can be selected by a volume button input between “pause” and “play”. Specifically, when “volume +” twice and “volume −” once are input continuously, the impression of the music is set as an impression of the pattern 21. Thus, the user can set the impression of music by inputting the above operation.

  As described above, the user can set the music being played back as the music to be operated on the file according to the registration generation rule in which the input operation combining the operations of the music operation input unit 90 and the file operation are associated with each other. it can. The operation conditions input to the music operation input unit 90 described above are merely examples, and combinations of operation buttons and combinations of operation conditions and file operations are not limited to these.

  As described above, when the registration generation rule is updated in the process of step S12, the control unit 40 performs the process of step S13 to generate a music list based on the updated registration generation rule or extraction generation rule. I do.

  In the process of step S <b> 13, the control unit 40 creates a music list based on the updated generation rule among the generation rules stored in the generation rule storage unit 50. For example, in the registration generation rule, the music corresponding to the generation rule name “delete from DB” is extracted from the history information stored in the history information storage unit 30 (for example, music skipped after being paused) (for example, The music number 56 corresponds to FIG. 2), and a music list is created. The generation rule names correspond to the item buttons 70-2 to 4 of the music list selection unit 28 shown in FIG. Therefore, when each item button in FIG. 11 is selected, a music list created by extracting music that matches each condition of the registration generation rule is displayed on the extraction list display unit 22 in FIG. When the music list is created, the process of the control unit 40 returns to step S1 again. In addition, after performing file operation with respect to the music list produced by step S13, it is good also as a process which returns to step S1 again.

(Embodiment 2)
FIG. 18 is a block diagram illustrating a configuration of a music playback system according to the second embodiment. The music playback system 100 has substantially the same configuration as that of the first embodiment, but is different in that the music list generation device 200 and the playback device 300 can be used separately. The music list generation device 200 is realized by a personal computer, for example. On the other hand, the playback device 300 is realized by a portable audio player. The music list generation device 200 and the playback device 300 are connected by, for example, USB (Universal Serial Bus).

  The music list generation device 200 includes a music database 10, a reproduction list storage unit 20, a history information storage unit 30, a control unit 40, a generation rule storage unit 50, a display unit 60, and an input reception unit 70. . When the music list generation device 200 and the playback device 300 are connected, the control unit 40 updates the history information of the playback operation stored in the history information storage unit 30 via the memory 95. The music list generation device 200 creates a music list by a process substantially similar to that of the above-described embodiment. In the present embodiment, the first music data storage unit corresponds to the memory 95, the history information storage unit corresponds to the history information storage unit 30, and the second music data storage unit corresponds to the music database 10. A music list generation unit, a music data processing unit, and a history information acquisition unit correspond to the control unit 40.

  The playback device 300 includes a playback unit 80, a playback control unit 85, a music operation input unit 90, and a memory 95. The memory 95 stores music data to be reproduced. The music data may be acquired from the music database 10 of the music list generation device 200 or may be acquired by another method. The playback unit 80 plays back music in response to a command from the playback control unit 85. At that time, the contents of the music operation input to the music operation input unit 90 during the reproduction of the music are stored in the memory 95 as history information. When the music list generation device 200 and the playback device 300 are connected, the control unit 40 updates the contents of the history information storage unit 30 using the history information in the memory 95. Specifically, when the history information of the same music as the music whose history information is stored in the memory 95 is stored in the history information storage unit 30, the history information of the music stored in the history information storage unit 30 is The history information stored in the memory 95 is updated. Further, when the history information of the music whose history information is stored in the memory 95 is not stored in the history information storage unit 30, the history information of the music stored in the memory 95 is newly stored in the history information storage unit 30. Added and stored. The music list generation device 200 creates a music list using the updated history information.

  In addition, the music list generation apparatus according to the present embodiment can create a music list based on the generation rules as in the first embodiment. Since the music list generation device 200 and the music playback device 300 can be used separately, the following registration generation rule may be registered. That is, a registration generation rule in which an input operation combining “pause” and “cue” and a file operation for “confirming information such as a song name” is associated with the music operation input unit 90 may be used. Thus, even when the playback apparatus cannot confirm the song name because it does not have a display unit, the user can set the song name as a song to be displayed by inputting the operation during playback. Specifically, the following procedure is performed. In other words, when the user wants to know the name of the song being played, the user first inputs the above operation into the song operation input unit 90 during playback. The input operation is stored in the memory 95 as history information. Thereafter, the history information stored in the memory 95 is stored in the history information storage unit 30 of the music list generation device 200 by connecting the playback device 300 and the music list generation device 200. Furthermore, the control unit 40 selects a music piece for which the above input operation has been performed as “a music piece whose music title should be displayed” based on the registration generation rule, and creates a music list. Thereby, based on the created music list, it is possible to display the song names of all the songs that the user wants to know the song names. By setting such a registration generation rule, even when the playback device and the music list generation device are used separately, it is possible to easily create a music list according to the purpose.

  As described above, the playback apparatus according to the present embodiment can record the contents of the music operation being played back as history information. Further, by connecting the music list generation device and the playback device, the content of the history information of the music list generation device is updated using the history information of the playback device. Therefore, even when the music list generation device and the playback device are used separately, it is possible to easily create a music list corresponding to various purposes. Also, by making it possible to use the playback device and the music list generation device separately, the music management can be performed in the music list generation device, and the music playback can be performed in the playback device. Therefore, it is possible to provide a music reproduction system that is convenient for the user.
