Thanks! I appreciate the feedback.
I actually was thinking along similar lines as you with respect to the music initially, haha. But I ended up deciding to go with something that was a little too dramatic because I was wanted the you to feel like you were doing epic even though you are just pushing balls around at the end of the day.
As far as being a thematic fit... well, my head-canon for background the game is something like "You made a deal with the devil to become the best pool player in the world, so he gives you this insane training. But if you lose the eight ball, he gets your soul." So if you just imagine that to be the case, maybe the music feels a little bit more appropriate for the situation at hand :P
