I have used this and to be honest it isn't all that.
If you want to beat mix then the best thing in my opinion is to work hard at getting it right and do it live, you will get a better responce fro your public too if they can see you mixing it up.
If however you want a playout system that will put songs back to back without dead air thenMixMeister is by far the best that I have found. You simply pick your tracks from the list on the left of the screen and drag and drop to the right. I have tried and used it many times out on the road and it will put a track into place within three seconds.
As I also work on a local radio station that has used various playout programs and have tried a fair few and MixMeister beats Ejay and web jocky hands down.
Hope this has helped.
