You scared the hell out of me. That was a loud song, I wasn't expecting it. Particularly the first note of the song, the bass drum, which is what scared me. Damn. I have my volume pretty low too.
Anyway, the review: 5/5 8/10 The triangle instrument or whatever was annoyingly... annoying? I liked the drums, they had a good drum n bass sound to them. The guitar was good as well, the bass guitar was SLIGHTLY too loud, it seemed in competition with the guitar. Which I suppose for a boss theme for a game, would turn out to be a good thing, given the right context. But for the song itself that was a little bad.
