The data of the same musical pieces are stored in the same order in each of a plurality of music playback apparatuses. When one music playback apparatus is instructed to finish musical-piece playback, it generates musical-piece playback information indicating the playback order of the musical piece being played at that time, and sends the musical-piece playback information to a mobile telephone. The mobile telephone receives the musical-piece playback information and stores it in its internal memory. When the mobile telephone is moved to a position around another of the music playback apparatuses, the mobile telephone sends the musical-piece playback information to the other music playback apparatus. When the other music playback apparatus is instructed to start musical-piece playback, it selects the musical piece to be played back next, according to the musical-piece playback information sent from the mobile telephone, reads the data of the selected musical piece, and starts playing back the musical piece.
