Try a few thousand...
My pick would be map 18, Waiting For Romero To Play. Not only is it yet another bastardized metal cover (This Love by Pantera), but it's first used in the kickass proto-slaught map The Courtyard, where it's creepy atmos doesn't fit (it does fit better with Monster Condo, tho). And I think it's the only track in Doom II (apart from the intermission text music) with no percussion whatsoever.
I still like it, though. The only Doom music I actually hate is TNT's map 14. Now THAT one sucks a Tom Hall 'nad.
