The AppleCD Audio Player is an application programme, commonly found under the Apple menu, that came on Macintosh computers with a CD-ROM drive built-in as of System 7. Its main utilities, beyond just playing a music CD, lies also in how the music is played. It can shuffle tracks, and you can even create your own playlist. The user can choose different tracks, choose whether the music should play once from beginning to end, or repeat, or shuffle, and even a playlist can be created and one song be played multiple times in the playlist.
