A self-contained and self-powered MP3 music storage device that may be used in place of an audio cassette and controlled by an unmodified audio cassette player. The device senses the direction and speed of rotation of the drive shafts of the audio cassette player to determine whether to play, fast forward, fast rewind, or stop playing music stored in the device and provides the appropriate sound signals to the audio cassette player through a magnetic head coupled to the tape playback head of the audio cassette player. To the audio cassette player the device appears to be a conventional audiocassette.
