The transition destination episode is determined based on the information.

Specifically, the above-described music reproducing device can be applied to a device capable of reproducing music such as a navigation device. The music playback device holds music information including music attribute information in advance. Here, the music attribute information refers to information such as a music release date and a genre. The music playback device also holds information related to the history played by the user.

The episode period setting means sets the episode period based on the user's specific information (for example, the date of birth) acquired by a predetermined method (for example, an input operation). Here, the episode period refers to a period divided into a plurality of user growth processes. For example, the episode period is based on an era such as “elementary school age”, “junior high school age”, “working person”, etc. To do. As described above, the episode setting means sets an episode period obtained by dividing the human growth process into a plurality of times.

The episode determining means determines an episode that is a target of the music reproduction list. The music reproduction list generating means generates a music reproduction list related to the episode determined by the episode determining means. And a change timing determination means determines the timing which changes the episode of a music reproduction list production | generation object with respect to the said episode determination means. For example, the change timing determining means determines that it is the change timing when a predetermined number of songs are reproduced for the same music reproduction list. The episode determining means determines the transition destination episode based on the user's psychological information (for example, the number of cancellations during music playback).

In this way, the music playback device divides and manages user episodes, provides music corresponding to the divided episodes, and changes episodes of the music to be provided at a predetermined timing.

The data storage unit 36 holds a map information DB 350, a music information DB 360, an episode division information DB 370, and the like.

The map information DB 350 is a map information database. The music information DB 360 is a database having music information and music attribute information (release date, etc.). Further, it is assumed that the music information DB 360 also holds the user's past reproduction history information. That is, the music information DB 360 functions as a reproduction history information holding unit. The reproduction history information here refers to information in which information related to the reproduced music (music name, music identification information, etc.) and the number of times of reproduction are associated with each other. The episode division information DB 370 is a database having episode division information. Episode division information here is information in which a user's episode and the duration of the episode are defined.

Here, the episode division information will be described with reference to FIGS. First, FIG. 3 shows a conceptual diagram regarding episode division. As shown in FIG. 3, the user's episode is divided (for example, “children”, “elementary school”, etc.) based on the input operation (for example, the date of birth) by the user. Note that the episode divided first is the episode hierarchy 1, and the episodes in the episode hierarchy 1 are changed to the episode hierarchy 2 and the episode hierarchy 3 according to various events (for example, when the number of times the corresponding episode has been played exceeds a threshold). Subdivide.

Fig. 4 shows an example of the data structure based on the conceptual diagram of Fig. 3. As shown in FIG. 4, the episode division information is information including an episode and a period of the episode.

The episode period setting unit 301 determines the user's growth process for a plurality of periods based on the user's specific information (for example, the date of birth) acquired via a predetermined input device (for example, a keyboard, a touch panel, etc.). Divide into In the present embodiment, as shown in FIG. 3, the episode period setting unit 301 sets the episode period based on a simple time segment in the age-related growth process such as “elementary school”, “junior high school”, “working person”, etc. Set and generate episode division information that is information about the set episode period.

Note that the present invention is not limited to this, and the episode period setting unit 301 may determine the episode period based on the time division in the psychological growth process (for example, “adolescence”, “adolescence”, “mature period”, etc.). May be set, or the episode period may be set based on a relative time segment (for example, 10 years ago).

The episode determination unit 302 determines an episode for which a music reproduction list is to be generated. Specifically, the episode determination unit 302 determines the transition destination episode according to various conditions based on the reproduction history information held in the music information DB 360. For example, when a song has not been listened to for a while and played back after a long time, it is played back from a relatively past episode (for example, elementary school or junior high school), and the current episode is automatically transitioned gradually.

The music reproduction list generation unit 303 generates a music reproduction list related to the episode determined by the episode determination unit 302 using the music attribute information managed by the music information DB 360.

The music playback unit 304 plays back music based on the music playback list generated by the music playback list generation unit 303.

The change timing determination unit 305 determines the timing for changing the episode of the music reproduction list. The determination method will be described later.

[Music playback method (1)]
Next, the music reproduction method (1) will be described. Here, the music reproduction method (1) refers to a method of transitioning again to the latest episode when the episode for which the music reproduction list is generated transitions from the latest episode to another episode.

In the music playback device 300, the episode period setting unit 301 sets a plurality of episode periods based on user-specific information (birth date information, etc.), and stores episode information related to the set episode periods in the episode division information DB 370. To do.

The episode determination unit 302 determines the transition destination episode using the reproduction history information. When the music reproduction list is not yet created, the episode determination unit 302 determines a predetermined episode as an episode for which a music reproduction list is to be generated.

Then, the music reproduction list generation unit 303 generates a music reproduction list for the episode determined by the episode determination unit 302.

Then, the music playback unit 304 plays back the music in the music playback list generated by the music playback list generation unit 303.

When the change timing determination unit 305 determines that it is the episode change timing, such as when the number of songs played based on the music playback list is equal to or greater than the threshold, the episode determination unit 302 displays the playback history information. The transition destination episode is determined according to various conditions based on, and the music reproduction list generation unit 303 generates a music reproduction list of the episode determined by the episode determination unit 302.

In addition, when the episode determination unit 302 changes from the latest episode “Society 2” to an episode other than “Society 2” as a result of changing the episode, the episode determination unit 302 determines that the episode is final. Then, the episode is determined so as to transition to the latest episode “working person 2”.

In this way, the music playback device 300 changes the episode several times and changes to the latest episode even when the episode changes in the music playlist as a result of changing to an episode other than the latest episode. be able to.

According to this, the music playback device 300 can avoid leaving the episode corresponding to the music to be played back soaked in so-called past memories by transitioning to the past episode. it can.

As described above, the music playback device 300 divides and manages user episodes, provides music corresponding to the divided episodes, and changes episodes of the music to be provided at a predetermined timing.

Generally, a person's growth process includes a stage of forming a preference for the person. At the same time, in this growth process, information on episodes and related places is stored as human memory. The user response in such a long span is effective. In addition, episodes are automatically transitioned at a predetermined timing, and music suitable for the user's psychology is provided.

This system captures information according to the user's growth process, captures the user's psychology from the playback history, automatically transitions episodes, and provides the optimal music. At the same time, the memory is aroused and the user can enjoy emotions such as “Energy”, “Relax”, and “Refreshing”.

However, it is not preferable to soak in the past memories too much from the viewpoint of escape from reality. Therefore, the above-described music reproduction device 300 controls to automatically return to the current episode when the episode for which the music reproduction list is generated transitions to a past episode.

FIG. 5A and FIG. 5B show an example in which an episode in the music reproduction list returns to the latest episode after transitioning from the latest episode to another episode.

In the example of FIG. 5A, after the transition from “working person 2” to “elementary school”, the transition is made continuously from “elementary school” to “working person 2”. In this case, the music playback device 300 provides music for consecutive episodes when transitioning from the latest episode to other episodes. A person can naturally recall memories and experiences and enjoy emotions such as “Energy”, “Relax” and “Exhilaration”.

In the example of FIG. 5B, after the transition from “working person 2” to “elementary school”, the working person 2 is discontinuously in the order of “elementary school”, “high school”, “high school”, “working person 2”. Transition to. Thus, by playing back discontinuously, the music playback device 300 can skip the episode when the playback time of the music does not reach a certain value or when the music evaluation is less than a certain value. . This makes it possible for the music playback device 300 not to play back music related to episodes of memories or experiences that are not so important to the user or that are not preferable, and that is more “good”, “relaxed”, “ Emotions such as “exhilarating” can be enjoyed by the user.

[Music playback method (2)]
Next, the music reproduction method (2) will be described. Here, the music playback method (2) means that the number of cancellations is counted when the music is played back based on the music playback list, and the transition destination is changed according to the counted cancellation number at the change timing. A method for determining episodes.

The episode determining unit 302 determines a predetermined episode as an episode for which a music reproduction list is to be generated.

Then, the music playback unit 304 plays back the music in the music playback list generated by the music playback list generation unit 303. If there is a cancel request while the music playback unit 304 is playing, the change timing determination unit 305 counts the number of cancels.

Then, when the change timing determination unit 305 determines that it is the episode change timing, such as when the number of songs reproduced based on the music reproduction list exceeds a threshold, the episode determination unit 302 The transition destination episode is determined in accordance with the number of canceled music pieces in the episode music reproduction list. For example, as shown in FIG. 6A, when the number of cancellations is large, the episode determination unit 302 makes a transition to an episode far from the episode of the currently played music. If the number of cancellations is small, the episode determination unit 302 makes a transition from the episode of the currently playing music to a near episode.

The music reproduction list generation unit 303 generates a music reproduction list of the episode determined by the episode determination unit 302, and the music reproduction unit 304 reproduces music based on the music reproduction list.

Thus, the music playback device 300 determines the transition destination of the episode according to the number of cancellations related to the music in the music playback list. According to this, as the number of cancellations increases, music from farther episodes is played back, so it is possible to provide users with fresh music compared to playing nearer episodes, and at the same time, farther in time. Recalling this memory, you can enjoy emotions such as “Energy”, “Relax” and “Exhilaration”.

It has been described that the episode determination unit 302 determines the transition destination episode according to the number of cancellations of the music in the music playback list of the episode before the change, but the transition from the current episode to the past or the current direction Whether to transit to is determined based on the following conditions.
(Condition 1) In the episodes at both ends (for example, “children”, “working person 2”), the transition direction is one direction.
(Condition 2) For episodes other than the above (Condition 1), follow the direction of transition to the current episode. That is, when the transition is made in the past direction, the transition is made in the past direction (for example, FIG. 6B), and when the transition is made toward the current direction, the transition is made in the current direction (for example, FIG. 6C). ).

In this way, since the music playback device 300 makes a transition according to the direction of transition, the music is replayed along the flow of time, so that the memory of the user is recalled in order. You can enjoy feelings such as “relaxing” and “exhilarating”.
Compared to simply making a transition according to the number of cancellations, the possibility that the user can reproduce the desired music is increased.

[Music playback process]
Below, the procedure of a music reproduction process is demonstrated using the flowchart shown in FIG. This process is realized by the system controller 20 of the music playback device 300 executing a program prepared in advance.

First, the input unit 60 acquires information such as the date of birth via a predetermined input device (for example, a touch panel or a voice recognition device) (step S1).

Then, the current time is acquired using the timer function provided in the music playback device 300 (step S2). Then, the episode period setting unit 301 sets a plurality of episode periods based on the user specific information (step S3). Then, the episode determination unit 302 determines the episode for which the music playback list is to be generated by a predetermined method (step S4), and the music playback list generation unit 303 plays the music corresponding to the episode determined by the episode determination unit 302. A list is generated (step S5).

Then, the music reproduction unit 304 reproduces the music based on the music reproduction list (step S6), and ends the music reproduction without stopping the episode transition, for example, when the music reproduction device 300 is turned off. (Step S7; Yes) If the music reproduction is to be continued (Step S7; No), the change timing determination unit 305 determines whether or not it is the timing to change the episode of the music reproduction list, and the music reproduction is performed. If it is not time to change the episodes in the list (step S8; No), the process proceeds to step S6, and the music is reproduced based on the generated music reproduction list.

If the change timing determination unit 305 determines that it is time to change the episode of the music reproduction list (step S8; Yes), the episode determination unit 302 selects the target of the music reproduction list based on a predetermined control criterion. (Step S9), the process proceeds to step S5, and the music reproduction list generation unit 303 regenerates the music reproduction list for the episode determined by the episode determination unit 302.

Then, as described above, when the music playback is to be terminated, such as when the music playback device 300 is turned off, the episode transition process is terminated without performing the episode transition (step S7; Yes).

In addition, when applying said music reproduction method (1) to said episode transition process, as a result of changing an episode, when changing from the latest episode to another episode, in step S9, the episode determination unit 302 is updated The episode for which the music reproduction list is to be generated is determined so as to be close to the episode.

In addition, when the above-described music reproduction method (2) is applied to the above-described episode transition process, in step S9, based on the number of cancellations until the episode determination unit 302 reaches the transition timing, the music reproduction list generation target Determine the episode.

In addition, you may make it apply said episode transition method (1) and episode transition method (2) simultaneously. For example, as a result of the episode determining unit 302 determining the transition destination episode based on the number of cancellations while determining whether it is the transition timing, the transition from the latest episode to another episode is made. In this case, after the next episode change timing, the episode determination unit 302 determines a transition destination episode so as to approach the latest episode.

[Stratified episode period]
In addition, the episode period setting unit 301 determines the hierarchy for the certain period when the song evaluation for a certain period (for example, the first semester of elementary school) within a predetermined episode period exceeds a predetermined threshold. Subdivided. Here, the music evaluation refers to the number of reproductions, evaluation information input by the user, and the like. Thereby, the music playback device 300 can generate a music playback list according to the hierarchical level.

For example, if the music reproduction list generation unit 303 changes the number of songs to be selected according to the hierarchical level, a music list centered on music that matches the user's preference can be generated.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. FIG. 8 shows a schematic configuration of a music playback device 300a according to the second embodiment. In addition, the same code | symbol is attached | subjected to the component same as the music reproduction apparatus 300 of 2nd Example shown in FIG. 8, and the description is abbreviate | omitted.

In the music reproducing device 300a in the second embodiment, the “episode period location information acquisition unit 306”, “living and living list information generation unit 307”, “position information acquisition unit 308”, “ A GPS receiver 18 ”is provided, and a living and living list information DB 380 for managing the living and living list information generated by the living and living list information generating unit 307 is held.

The living and living list information DB 380 includes living and living list information, which is information that associates the episode division information including the user's episode and the duration of the episode with the location of the episode.

Here, the living and living list information will be described with reference to FIGS. 9 and 10. FIG. 9 is a conceptual diagram showing the relationship between the episode period and the location corresponding to the episode. As shown in FIG. 9, the user's episode is divided (for example, “children”, “elementary school”, etc.) based on the input operation (for example, the date of birth, etc.) by the user. Note that the episode divided first is the episode hierarchy 1, and the episodes in the episode hierarchy 1 are changed to the episode hierarchy 2 and the episode hierarchy 3 according to various events (for example, when the number of times the corresponding episode has been played exceeds a threshold). Subdivide. And the music reproduction apparatus 300a acquires the place regarding the said episode by input operation etc. by a user. Then, the music reproducing device 300a associates the episode period with the place related to the episode.

FIG. 10 shows an example of the data structure based on the conceptual diagram of FIG. As illustrated in FIG. 10, the living and living list information is information including an episode, a duration of the episode, a place related to the episode, and range information of the place related to the episode. The range information of the place regarding the episode here may be defined according to the input operation of the user, or may be defined by the music reproducing device 300a. In the present embodiment, the music reproducing device 300a determines the range information according to the degree of distribution of places corresponding to each episode period. For example, if the place in the list of living and living is a relatively wide area (high degree of dispersion) that covers “Hokkaido” and “Kyushu”, each area information is large, and conversely a narrow area such as the same city. If the degree of dispersion is low, the range information is reduced.

According to this, since the range of the location corresponding to the episode is too wide, the music reproducing device 300a is supposed to correspond to a plurality of episode periods at the same position, or the range of the location corresponding to the episode is narrow. It is possible to avoid that the position corresponding to the episode is limited by being too much.

The episode period location information acquisition unit 306 acquires location information corresponding to the episode period based on user input information and the like.

The living and living list information generating unit 307 generates the living and living list information in which the episode period setting unit 301 associates the set episode period with the location information corresponding to the episode period acquired by the episode period location information acquiring unit 306. Generate.

The location information acquisition unit 308 acquires location information (latitude and longitude information) of the music playback device 300a via the GPS receiver 18.

In the second embodiment, when the position information acquired by the position information acquisition unit 308 is not included in the range information of the living and living list information that the position information acquisition unit 308 acquires, the position of the music playback apparatus 300a A music reproduction list of past episodes corresponding to a distance from a place registered as any one of the living and living list information is generated.

For example, it is assumed that the point P1 shown in FIG. 11 corresponds to “working person 2”, and the point P2 and the point P3 do not have corresponding living and living list information. Thereby, it is determined that the point P2 and the point P3 are unvisited places.

In this case, when the user is at a relatively close point P2 from the point P1, a music reproduction list for the episode of “High School” is generated. When the user is at a distant point P3, the music reproduction list for the episode of “Primary School” is generated. Generate.

According to this, the music reproducing device 300a moves to an unvisited place, that is, when it is a stress relieving means such as driving or traveling, or when expectation and anxiety such as moving are mixed, etc. By playing from past episodes, the user can be reminded of past experiences and memories as well as nostalgia, and effects such as “Energy” and “Relax” can be brought about.

As described above, the music playback device 300a generates a music playback list according to the distance between the reference position and an unvisited place, with a place registered as any living and living list information as a reference position. Although the transition destination of the target episode is determined, a location corresponding to the latest episode may be set as the reference position.

[Music playback process (2)]
Below, the procedure of a music reproduction process (2) is demonstrated using the flowchart shown in FIG. This process is realized by the system controller 20 of the music playback device 300 executing a program prepared in advance.

First, the input unit 60 acquires information such as the date of birth via a predetermined input device (for example, a touch panel or a voice recognition device) (step S11).

Then, the current time is acquired using the timer function provided in the music playback device 300 (step S12). Then, the episode period setting unit 301 sets a plurality of episode periods based on the user specific information (step S13). And episode period place information acquisition part 306 acquires the place information corresponding to an episode period by input operation by a user, etc. (Step S14). Then, the living and living list information generating unit 307 generates living and living list information (step S15).

Then, the position information acquisition unit 308 acquires the position information of the music playback device 300 (step S16), and the episode determination unit 302 searches for the living and living list corresponding to the position information, and the episode of the corresponding living and living list. Is determined as an episode for which a music reproduction list is to be generated (step S17). And the music reproduction list production | generation part 303 produces | generates the music reproduction list based on the episode of the life residence list information which has the location information corresponding to a positional information (step S18). Then, when the music playback unit 304 plays back the music based on the music playback list (step S19) and no termination request such as turning off the power of the music playback device 300 is made (step S20; No), the change timing is determined. The unit 305 determines whether or not it is the episode change timing, and if it is not the episode change timing (step S21; No), the unit 305 moves to step S19 and continuously reproduces the music based on the music reproduction list. When the change timing determination unit 305 determines that it is the episode change timing (step S21; Yes), the position information acquisition unit 308 acquires the position information again (step S22), and corresponds to the re-acquired position information. If there is no life residence list information having location information, the episode determination unit 302 determines the transition destination episode based on the distance between the position information reacquired by the position information acquisition unit 308 and a predetermined reference position. (Step S23), the process proceeds to Step S18, and the music reproduction list generation unit 303 generates a music reproduction list based on the transition destination episode (Step S18).

Then, when the music playback is to be terminated, such as when the music playback device 300 is turned off, the music playback process is terminated without performing the episode transition (step S20; Yes).

As described above, the music playback device 300 includes music information holding means for holding music information including music attribute information, episode period setting means for setting a plurality of episode periods based on user-specific information, An episode determination means for determining an episode for which a music playback list is to be generated, a music playback list generation means for generating a music playback list of music related to the episode determined by the episode determination means, and a music playback based on the music playback list A music reproduction means; and a change timing determination means for determining a timing at which the episodes to be generated by the music reproduction list are changed with respect to the episode determination means. The episode determination means is based on psychological information of a user. To determine the destination episode.

Thus, the music playback device 300 divides and manages user episodes, provides music corresponding to the divided episodes, and changes episodes of the music to be provided at a predetermined timing.

Generally, a person's growth process includes a stage of forming a preference for the person. At the same time, in this growth process, information on episodes and related places is stored as human memory. The user response in such a long span is effective. Moreover, at a predetermined timing, the episodes to be generated by the music reproduction list are automatically shifted based on the psychological information, and music suitable for the user's psychology can be provided.

In the above first embodiment, the number of cancellations functions as psychological information. In the second embodiment, “the distance between the position of the music playback device 300a and the place registered as one of the living and living list information” "Functions as psychological information.

Also good. In this case, the music playback device 300 can generate a music playback list according to the degree of subdivision. For example, the music playback device 300 may preferentially include songs in an episode period with a high degree of subdivision (short episode period) in the playlist.

In the above-described embodiment, the case where an episode at a predetermined time is associated with the location of the episode has been described. However, the present invention is not limited to this, and a plurality of locations may be defined in the same episode. For example, an episode of “working person” may be associated with an address or associated with a work location.

In the above-described embodiment, the case where an episode of a certain length of time is associated with the location of the episode has been described. However, the present invention is not limited to this, and a temporary event (for example, summer vacation, birthday, You may make it match | combine with the place of the said episode as a homecoming etc. as an episode.

In the above-described embodiment, the case where the position information acquisition unit 308 specifies the position of the music playback device 300 using the GPS receiver 18 has been described. However, the present invention is not limited thereto, and predetermined position information is obtained. You may make it specify using IC card (for example, watermelon (trademark)) which can be acquired, wireless LAN spot information, etc.

In the above-described embodiment, the case where the episode determination unit 302 determines the transition destination episode according to the number of cancellations has been described. In this case, the number of playbacks is referred to by referring to deeper episodes or playback history information. You may make it change to an episode with many. At this time, as described above, when the transition is made in the past direction, the transition is made in the past direction, and when the transition is made in the current direction (latest direction), the transition is made in the current direction.

In the above-described embodiment, the case where the episode determination unit 302 determines the transition destination episode according to the number of cancellations is described. However, the present invention is not limited to this, and the episode before the transition is the latest episode ( In the above-described embodiment, in the case of “Working Person 2”), another piece of music that is not held in the music information DB 360 may be downloaded via the communication device 38 without changing the episode.

Although not particularly described in the above-described embodiment, when there is an input operation by the user while the music is being reproduced and a music reproduction request corresponding to the episode in the current direction is generated, the episode determination unit 302 The subsequent episode transition direction may be changed to the current direction, or the speed of transition to the latest episode may be increased. In addition, when the input operation by the user is a reproduction request for a song corresponding to an episode in the past direction, the episode determination unit 302 transitions to the latest episode while passing through many past episodes. You may do it.

In the above-described embodiment, the case where the evaluation information is the number of times of reproduction or information input by the user has been described. However, the present invention is not limited to this, and repeat or cancellation may be used as the evaluation information. Note that a button for inputting repeat or cancel may be provided in the music playback device 300.

Although not particularly described in the above embodiment, the episode determination unit 302 may notify the changed episode content via the audio unit 50 at the timing of transition of the episode. For example, the guidance is “I am in elementary school” or “I am in college”. Thereby, the music reproducing device 300 can explicitly notify the user of the episode change.

In the above-described embodiment, although not particularly described, when the user has not listened to the music for a while, or when playing the music after a long time, it is played from a relatively past episode (for example, elementary school, junior high school) You may automatically make a transition to the episode. In other words, the longer the time that the music is not listened to, the longer the past episode. Specifically, when the episode determination unit 302 refers to the music playback history information and determines that it has not been played back for a predetermined period, it determines a relatively past episode as an episode for which a music playback list is to be generated.

As described above, when the user has not listened to the music for a long time, the music playback device 300 plays back from a relatively past episode (for example, elementary school or junior high school), and automatically transitions to the current episode gradually. . When the user is too busy to listen to the music or when he / she is depressed, the music playback device 300 reproduces the past experiences and / or Recalling nostalgia with memory, you can enjoy positive emotions.

In the above embodiment, the case where the change timing determination unit 305 counts the number of cancellations has been described. However, the present invention is not limited to this, and the number of cancellations may be counted by other means.

In the above-described embodiment, the episode determination unit 302 of the music playback device 300a is a distance between the position of the music playback device 300a and a location registered as any living / living list information (hereinafter also referred to as an episode-corresponding location). However, the present invention is not limited to this, and the episode determination unit 302 determines the distance and the degree of dispersion of the position of the location corresponding to each episode. You may make it determine the episode which changes using the information calculated based on.

FIG. 13 (a) and FIG. 13 (b) show examples of the degree of distribution of episode-corresponding places (P11a to P15a and P11b to P15b) of each user. As shown in FIG. 13 (a), the episode determination unit 302 of the music playback device 300a starts from the location corresponding to the episode for the user in which the location corresponding to the episode is distributed. Even if you go to an unvisited place that is a little far away, it is judged that there is no psychological burden, and you do not make a transition to a far away episode. Then, for a user whose episode-corresponding places are crowded like the degree of dispersion of the episode places shown in FIG. 13B, the episode determining unit 302 of the music playback device 300a places the place corresponding to the episode. Even if you go to an unvisited place that is a little far from, it is judged that a psychological burden is applied, and the transition is made to a slightly separated episode.

According to this, the music playback device 300a corresponds not only to the “distance between the position of the music playback device 300a and any location registered as any living and living list information”, but also to the user's past episodes. Since episode transition is performed using information that can estimate the psychological burden on each user's movement, such as the degree of variance of the place, considering the difference in psychological burden on movement to unvisited places for each user, Episode transition can be done.

In this case, the information calculated based on the above distance and the degree of dispersion of the location of the location corresponding to each episode functions as psychological information.

In the above-described embodiment, a case has been described in which the change timing determination unit 305 determines that it is the episode change timing, such as when the number of songs played based on the music play list exceeds a threshold value. However, the present invention is not limited to this, and the change timing may be determined based on the number of cancellations and the reproduction time.

In the above-described embodiment, the case where the music reproducing device 300 is applied to a navigation device has been described. However, the present invention is not limited to this, and can be applied to various audio players such as a mobile phone capable of reproducing audio.

The present invention can be used for various music playback devices that play back a large number of music stored in a storage medium, such as a mini component, a portable audio player, a car audio, a karaoke device, and a mobile phone.
