A candidate piece specifying unit 6 specifies, as a first candidate piece, a musical piece whose musical piece parameter includes a first factor that is larger than a first factor of a musical piece currently being played from among musical pieces, and specifies, as a second candidate piece, a musical piece whose first factor is smaller than the first factor of the musical piece currently being played from among the musical pieces. When data of a musical piece is reproduced by a playback unit 4, a display control unit 8 causes musical piece information regarding the first candidate piece and the second candidate piece to be displayed at positions on a display screen that reflect coordinate positions in an impression space formed by the factors of the musical piece parameter. Upon receiving an input from a user of specifying a musical piece indicated by musical piece information displayed on a display device 10, a playback control unit 5 controls data of the specified musical piece so that the data of the specified musical piece is reproduced by the playback unit.
