I didn't know they had audio! Thanks for pointing me in that direction. I found some cool stuff, and I think I'm going to go with a largely percussion focus for KarBOOM's music.

EDIT: At Error014's suggestion, I'm going to try and have the music depend on the action. This will at least mean the overall intensity of the action, but ideally other aspects and particular events will trigger unique parts of music. I'll let you all know how it goes.

Btw, I finally got myself a copy of the issue of PC Gamer that had KarBOOM in it so I could see what section featured it. It's called "Top 10 Downloads"
