Abstract

A song in a music player is replaced by another song in a server in accordance with the user's estimated preferences and wishes and without requiring the user to become conscious of individual songs. A CPU () in the music player () or a CPU () in a server () detects or receives the size of a free space in a flash memory () and a playback history (a substantial playback count Kp, which denotes the number of times a song was continuously played for a duration not shorter than a predetermined one, or a skip count Ks, which denotes the number of times a song was played for a duration shorter than a predetermined one) of every song recording in the flash memory (), and judges whether any song should be deleted from the flash memory () to permit a song to be downloaded into the music player () from the server (). If any song should be deleted, the CPU selects a song having a small (minus) evaluation function K (e.g., K=2Kp−Ks) as the song to be deleted.
