This is great Music that I want to use in my indie games, and I wanted to make sure that adding "Music By TempoSmith" would work in a commercial game?

I'm a late in responding, but I want to post this so others know a definite answer as well. The only requirement is credit, even in commercial games. No royalties or anything are required. Just credit TempoSmith where applicable.
