A few months back, I put on a big search for some sort of MP3 mixer for my photo shows. I found some that were OK, but nothing that really did the job. I'm looking for something that will let me blend one song into the next, but does so in such a way as I can match the beat. I found a few that let me fade the songs together, but it was a hit and miss affair consisting of nuding the track back and forth until luck got it in sync.

It would also help if it was inexpensive and easy to use.
