10. Mario Soundtacks -> In perticular Super Mario Galaxy 2, but all are instant classics.

9. Uncharted 2: Among Thieves -> The quality and urgency in all of the original tracks on this soundtrack is incredible. If you haven't played it, stop reading this and go now.

8. NiGHTs Into Dreams -> Surreal and fantastic in nature, although drives some crazy it is incredibly light hearted, definitely deserves this spot.

7. Shadow of the Colossus -> A very natural soundtrack, but at the same time it has the epicosity of hunting the next colossi.

6. Chrono Trigger -> Probably one of the more memorable soundtracks of all time, just because of the fact that a dream team of developers that deserved an equal soundtrack for their game.

5. Donkey Kong 64 -> Dong Key Kong! All of the tracks from this are superb and original, not to mention the DK rap.

4. FF7 -> Nobuo Uematsu's greatest music score to date, and easily the best in the series.

3. Command & Conquer Red Alert, Counterstrike, and The Aftermath -> For King and country! These games are what rts gamers between the age of 17 and 23 grew up on. If it were to come on somewhere you would suddenly get really intense about whatever you are doing. This is not to say that the other C&C games don't have a good soundtrack, these were just the best.

2. Afro Samurai -> This is one of the most unique soundtracks to any game I've ever played, it also stays very true to the original anime show and movie. Hours of original hip-hop tracks that pull you right into the game.

1. World of Warcraft -> I know, I know, hate away but this game has some of the most epic music for all occasions. Walking into a city has never felt like you were part of a war effort.

Mass Effect, especially number II

"The attack" (http://www.youtube.com/watch?v=GW8x8I8k ... re=feedlik)
"Suicide Mission" (http://www.youtube.com/watch?v=VTsD2FjmLsw)

Those are my personal favorites.

*EDIT* I'm adding Scott Pilgrim vs. The World, amazing OST. Just listen to this- http://www.youtube.com/watch?v=Wqv5wxKDSIo

I can't believe no one has put any of the DJ Hero(s)!

Those "games" don't count.

The Scott Pilgrim game ost was good, but doesn't really compare to Anamanaguchi's other albums.

Wait... No one has mentioned Katamari Damacy... One of the most fun and varied soundtracks ever.
