  A specific example of music reproduction when passing through a predetermined point on the taxiway will be described. The music processing device 50 may be mounted on a car navigation device like the head unit 11. When a user drives with a car equipped with a car navigation device, when he / she departs by setting a destination and searching for a route, the travel time and the passing point and the expected time of passing through each passing point are found. Based on this, the playback order on the playlist is determined.

  For example, suppose you drive from Tokyo Station to Izu via Shonan Coast. We gathered at Tokyo Station and conducted a route search by using a car navigation system with Izu as the destination and Shonan Coast as a waypoint, and set up this drive course. The car navigation apparatus calculates an expected passing time of each passing point on the taxiway along with the taxiway. A playlist that reproduces music related to the sea can be created at the time of creating the playlist when it passes the Shonan Coast based on the expected transit time.

  The music processing device 50 may further include current location detection means 63. The current location detection means 63 detects the current location using GPS or the like. The reproduction means 57 reproduces music that is registered in the playlist and is related to the current location. In a typical playlist, the music titles are arranged from top to bottom in the music playback order. However, when playing music related to the current location, the playback order on the playlist is changed as appropriate. For example, when the current location is a road with a view of the sea, music related to the sea is selected from the playlist and played back. The detection timing of the current location is typically shortly before the reproduction of the music related to the current location starts, for example, when the previous music is being played and the next playback music is determined.

  The music processing device 50 also determines a predetermined selection condition based on the music held by all of the music processing device 50 and the portable music playback devices 51a, 51b, 51c,. A predetermined music corresponding to a predetermined selection condition may be selected from the music held by one of the playback devices 51a, 51b, 51c. That is, the music that matches the selection condition is performed from the music processing device or one portable music player. However, even in that case, in order to reflect the preference of the entire group, the selection condition is based on the music that the whole, that is, the music processing device 50 and the portable music playback devices 51a, 51b, 51c,. Decide.

  The music processing device 50, when the same music is selected repeatedly from the music processing device 50 and the separate portable music playback devices 51a, 51b, 51c, ... and registered in the playlist, the same music Among them, the reproduction order of the second and subsequent ones is reproduced as it is or the reproduction is skipped. When skipping playback, the user does not have to listen to the same music repeatedly. If the music to be skipped is Cr2 in FIG. 6 for overlap selection, instead of skipping Cr2, for example, Cr3 may be played back, that is, the portable music playback device in which the skipped music is selected Therefore, the music whose playback waiting order is next to the skipped music is played instead of the skipped music. Furthermore, if the music to be skipped is Cr2 in FIG. 6 for overlapping selection, instead of skipping Cr2, for example, Crx may be played back. Crx is the mobile phone in which the skipped music Cr2 is selected. Although it is a song owned by the type music player c and corresponds to the current selection condition, it is a song that has been omitted from registration in the playlist in FIG.

  In a certain music processing device 50, the playlist creation means 56, when the same music is selected redundantly from the music processing device 50 and different portable music playback devices 51a, 51b, 51c. A playlist may be created so that only one of the selected songs is registered. The fact that it is not registered redundantly in the playlist means that the same music is not repeatedly reproduced. Here, the playback order determining means 60 determines the playback order of the music in which only one of the music selected in duplicate is registered in the playlist before or after the other music without the redundant selection. May be. Then, the playlist creating means 56 creates a playlist in which the selected music pieces are arranged in the determined reproduction order. The reproduction means 57 reproduces music based on the reproduction order on the playlist. As a result, the reproduction of the musical piece in which only one of the redundantly selected musical pieces is registered in the playlist is reproduced first or last.

  When the playlist creation means 56 selects the same music from the music processing device 50 and the separate portable music playback devices 51a, 51b, 51c,..., One of the music selected by duplication is displayed. An additional note about creating a playlist so that only one is registered. The group members are three users A, B, and C, and the portable music player devices 51a, 51b, and 51c are owned by the users A, B, and C, respectively. In the playback order of the music playback based on the group playlist, for example, the selected music from the portable music playback device 51a → the selected music from the portable music playback device 51b → the selected music from the portable music playback device 51c → the portable type. The selected music from the music reproducing device 51a may be used in order of reproducing the selected music from the portable music reproducing devices 51a, 51b, 51c one by one in a circulating manner. Assuming a temporary user X separate from users A, B, and C, assuming a temporary portable music playback device x owned by the user X, only one of the redundantly selected music pieces is played because of the redundant selection. The music registered in the list is regarded as the selected music from the portable music playback device x. Then, in the playback order of the music playback based on the group playlist, the selected music from the portable music playback device 51x → the selected music from the portable music playback device 51a → the selected music from the portable music playback device 51b → the portable type. Reproduction that reproduces the selected music from the portable music reproducing devices x, 51a, 51b, and 51c one by one in a circulating manner from the selected music from the music reproducing device 51c to the selected music from the portable music reproducing device 51x. The order may be adopted.

  The music selection means 55 selects the music from the music processing device 50 and the portable music playback devices 51a, 51b, 51c,. exclude. As a result, the user can listen to music that the user does not have.
