Abstract:
1. A music data transfer/recording method for transferring song data from a server, which retains song data in a storage device, to a music player, which plays back song data retained in a storage section, and writing the transferred song data in the storage section, the method comprising: a first step for causing the server to select the song data to be transferred to the music player from among the song data that are retained in the storage device and not retained in the storage section; a second step for causing the music player to judge whether the free space in the storage section is exceeded by the amount of song data to be transferred; and a third step for causing the music player, when the free space in the storage section is exceeded by the amount of song data to be transferred, to select the song data to be deleted from the storage section, delete the selected song data from the storage section, and write the song data transferred from the server into the storage section, wherein the first step causes the server to select song data that has not been transferred to the music player and has been most recently registered in the server, as the song data to be transferred to the music player; and wherein the third step causes the music player to reference a continuous playback count of each song data retained in the storage section, the continuous playback count denoting the number of times a song was continuously played for a duration not shorter than a predetermined one, or a skip count of each song data retained in the storage section, the skip count denoting the number of times a song was played for a duration shorter than a predetermined one, and select the song data having a low continuous playback count or the song data having a high skip count as the song data to be deleted from the storage section.
