could you make it so that you could customize it so that you could have specific soundtracks only play for combat or ambient?

for example; I want to have doom music play when I'm in combat, but have Earth Bound music playing for ambiance, instead of Doom's dark ambiance. in addition, I don't want Earthbound music playing when i'm in combat. It would be nice to be able to set separate soundtracks to play for ambiance or combat, with out having them overlapping.
