Battle music suggestion

I had to think about the battle music again.

And I don't think it would be a good idea. It would somehow take away from the rawness.
The fact that the battle is rather quiet intensifies the whole thing.

First you hear the heartbeat, then someone comes roaring, then the echoing bang of the gun, and then total silence. Adding battle music here would somehow kill the atmosphere.

Maybe in dungeons against skeletons. Or in hell. But only very subtly.
I don't know, but I feel like the ambient sounds here contribute much more to the atmosphere than if there were battle music.
