Me too man, but I usually create my own using midi. Another fun thing to do and is also great practice for your improv skills. Popping in a cd, play a track and put your own thing to it. Just make sure your in the right key, and your putting something over it that goes with it good. I do this all the time just for fun. :) Try playing along with a song you've never heard before. Great practice for when to get together with friends and just jam. I always get into situations like that. :)
