I know exactly which part of the movie you're talking about. It shocked me when I heard it, lol. I'm not too sure which band it is, but I'm leaning towards Metallica (I've never listened to them) because a friend of mine once said that the intro to Divine was very similar to a Metallica song.
Oh, and yeah, like the others have said, that part was actually taken from a classical piece anyway, so it's not like SX is ripping off other bands.
