Left 4 Dead/Awesome Music

"I think I speak for all of us when I say I understand Why you folks might hesitate to submit to our demands... But here's an FYI: You're all gonna die screaming! * cue zombie swarm*"
 * Left 4 Dead's main tune was a sorrow filled piece, that made you realize that many have died from the Zombie Apocalypse, wondering if you will be the exception. At the end, when the chopper/APC/boat arrives, the music seems to be shouting "COME ON! YOU CAN DO IT! SHOW THESE ZOMBIES!". Your teammates are being attacked by hunters, barfed on by boomers and thrown across the map by tanks, but you are still getting to the vehicle. The AI director is throwing everything it has at you, but you keep running. Once you get to the vehicle, you feel like you really accomplished something. L4D2's main tune sounds like something, really, really horrible happened in the last 5 seconds, and this is the aftermath.
 * Listen to it here
 * The Hard Rain rendition of the menu theme. Once you listen to this version, you'll never go back!
 * One better. The jukebox in L4D2 not only plays Re: Your Brains by Jonathan Coulton, it also spawns a wave of zombies on you. Paranoia Fuel, anyone?
 * Bear in mind, it's not that the song spawns zombies, it's when the song spawns zombies:


 * What about L4D2's version of the Skin on Our Teeth music mentioned above? The second that badass track starts you feel like if you don't haul ass NOW some completely gruesome and epic thing will happen to you, as opposed to L4D1's version that seems to go:"You can do it!"
 * The first version tells you that you can escape. The second version tells you that if you don't get out of there now, you are dead. And there are several hundred zombies in your way.
 * What could beat the Tank Theme? Why, it would be the Midnight Riders Tank Theme. Not to mention Xenogenocides unoffical Metal Tank
 * You seem to be forgetting The other Midnight Riders Tank Theme.
 * Ladies and gentlemen, I present to you the song from the Zombie Survival Guide trailer for Left For Dead 2: Chocolate Helicopter
 * Is there really no love for The Parish's Horde Theme? The frantic trumpet makes it sounds like you're in a surprisingly fun mad dash as you slash and shoot your way through -- exactly what most Horde encounters are.
 * And In The Parish,
