I have many, many, many more. I also have a bunch of German techno-ish stuff which is excellent for running. In fact, I have a separate playlist just for when I'm running intervals, to keep me motivated!
It has only the fast music from my regular list on it.
If you go over to the Exercise forum, there were a couple threads about music a while back. My current favorite workout song is "What you waiting for" though, it's very motivational!
