Game soundtracks.

Half-Life series ah, fuck it. Every later Valve game has got a exceptional soundtrack.
Call of Duty series (except WaW, I believe I became tonedeaf for a week after playing that game)
Halo series
Company of Heroes
BioShock
World in Conflict
Fallout 3 (Main theme stands for aprox 90 % of the election)

...And now I have probably listed every game in my gaming arsenal. Except Halo of course...

OH COME ON ! Only one guy said Red Alert 2! WHATS THE MEANING OF THIS?? Also I need to add Killing Floor alongside with RA2. RA2 musics are a LEGEND.

Beyond Good & Evil, I love its soundtrack.

 

[Blow_Pop]

The Team ICO games and the Silent Hill games

The Katamari soundtrack is cool.
