MUSIC!

I've begun employing music for a Deathwatch campaign I'm running, and my players tell me that's added a lot to the experience, having a soundtrack for encounters and key events. What say you, /tg/? Do you use music during your games? If so, what do you use?

Currently, I'm using a lot of this stuff:

Aliens Delux Edition Soundtrack
E.S. Posthumus
Immediate Music
King Arthur Soundtrack
Terminator 2: Judgement Day Sountrack
Terminator Salvation OST
The Chronicles of Riddick OST
Two Steps from Hell - Invincible
Two Steps from Hell - Nemesis
Starship Troopers OST

I highly recommend all of the above, but the E.S. Posthumus and Two Steps From Hell are just about perfect for SPEHSS MUHREENS!
