I know a song if you want a spooky level...

Try getting your hands on this little fella:

MayheM - Freezing Moon

It's very dark and has a fast riff 2.

For a quiet level:

MetallicA - The Call Of Ktulu

For a level with lot's of action:

Slayer - Reign In Blood

For another spooky level:

Cradle of Filth - Dinner At Deviant's Place (SERIOUSLY, listen to this one please)

Now bare in mind,
all of these tracks are a lot harder then wannabe Metal like Limp Bizkit and Linkin Park, but u'll get used to it!
