From God (no pun intend... okay, pun intended)
Upon first playing the game, I've heard the music drifting off in the background, paying little attention to it. On that note, at the time I was not actually into the game. When I returned and began to play the game, the music just caught me. It sets the perfect atmosphere for the game. The music is almost depressive at points, which puts you in this trance. It often makes you wonder... wonder that perhaps there are mysteries to this life... or what comes from "god". Whatever it is, the music kicked a lot ov ass!
