SUMMARY OF THE INVENTION Currently produced S
The capacity of the D card is 64 MB at the maximum, but an SD card having a capacity of 1 GB is expected in the future. This is a capacity that can record 100 songs or more for a song of about 5 minutes, and it is hard to imagine listening to 100 or more songs continuously at home. Then, it is considered that the user registers several songs in the playlist and listens to only the songs registered in the playlist. In other words, it can be easily inferred that the SD card is used as if several CD albums are contained in one card.

For example, consider a case in which the user gets tired of listening to all the songs (assuming one CD album) registered in a certain playlist and wants to replace the entire song with a new CD album. In this case, the processing shown in FIG. 11 described in the related art is required, and the operation of designating the music has to be repeated by the number of music.

[0015] When all contents of one playlist are added to another playlist,
Designation of all songs registered in one playlist had to be repeated for the number of songs.

As described above, in the conventional software that handles data conforming to the SD audio standard, editing processing (inputting character data, deleting / moving / copying music data, and changing to a playlist) that requires an input operation for each music piece is performed. Registration, etc.) has been realized, so even if you want to perform the same editing process on all the songs registered in the playlist, you must repeat the song designation work by the number of registered songs However, there is a problem that it becomes a burden for the user.

The present invention solves the above-mentioned problems, and can simplify the work (operation) of the user when the same editing process is performed on all the songs registered in the playlist. It is an object to provide an editing device.
