If you have more that one CD changer, or are utilizing MP3 or other PC-based music
files, it is possible to eliminate gaps in your music playback due to the time required to
change discs in the player(s). By insuring that consecutive songs are on different
players, CDJ can achieve continuous playback. CDJ can automatically alternate changers in
the shuffle mode or can optimize your own playlists by pressing the icon on the playlist
toolbar. This feature attempts to make your playlist alternate players with minimal
re-arrangement in the play order.
