That's what I originally thought as well but actually doing karaoke from a DJ program doesn't work very well. The reason is that even if you don't manage a complex rotation - karaoke really demands at least a playlist with the singer's name and the ability to change those associations (song-singer) on the fly. Without it you will end up needing a pen and paper and a lot more hassle than you really want.
I later adopted Siglos karaoke Pro as my karaoke player. It's so simple you can teach your mother to run it in under 5 minutes. You can use a rotation or a playlist and either one will give you the ability to manage singers right along with your tracks and retain information about any venue or group of singers to be recalled at a later show.
