Most of these backing track/karaoke disks are in CDG/CD+G format (which is also known as CD+Graphics format). These disks can be played on regular audio CD players, making them ideal for use as backing tracks. In addition to this, when they are played on special karaoke CD+G players, the lyrics are also displayed on the karaoke video screen which is attached to the karaoke system, making them idea for karaoke and sing-along performances.

Some professional backing track disks contain two versions of each song: one version with guide/lead vocals and the other version without lead vocals. This can be extremely useful when, for example, rehearsing a song for an audition or a show. Remember to check the detailed description of each disk if you are particularly looking for disks which contain lead vocals in addition to just the backing tracks (we recommend Pocket Songs disks as the most comprehensive disks for professional singers and vocalists).
