Try Rockit. The owner lives here.
I am a Serato lover myself, but I decided to stick to the cd format for my cdj's and will be adding a Denon 2500 for the back up stuff.
If I went didgital I would use Rockit and a good controller.
I use two 8-track players, and Victrola 2.0
I try out also the Ableton Live 6.0.Its a bit more complicated but you can make Remixes on the fly.I think it can play 128 tracks,loops...at once if youre computer can do that.
Dj Tiesto,Sash,BT and many else use this program at gigs.
