If you're an Xbox 360 user, or if you're a PC user, what are your favorite songs/artists to blast while playing?

A few of my favorites would be:

1.) Vivaldi - Four season (Winter is the best)
2.) Rachmaninoff - Anything really, just loop my collection
3.) Midnight Syndicate - All; check them out on YouTube, they're amazingly creepy
Others, I can't think of
