I still think that "Turrican 2" on Amiga has the best VG-Soundtrack.

There is no better video game soundtrack than that of Super Castlevania IV.  This clip barely covers a 10th of the tracks.

I know.  I used to play the last boss battle on the GC version over and over to listen to this song.  It's called Live and Learn by Crush 40 and its so awesome.   

I absolutely adore the main Halo theme. Few games have music that so perfectly fits the environment and feel of the title.

I'm also a sucker for the a capella SMB theme from the Secret Levels in Sunshine.

I actually downloaded that song after hearing it in Brawl.

And btw the best video gme soundtrack is Super Smash Bros. Brawl

Sound cool, but I perfer old school Kirby music, I like it

I like lots of the previously mentioned music. FFVII's One Winged Angel really got to me.

Otherwise I'm amazed noone mentioned Still Alive, portal ending credits. It is just the perfect ending song for the game. First time I ever replayed a game just to get to the ending.

Hrm, I'm really fond of the Earthbound Soundtrack ^^; seems to fit the mood of the game really well.

Same with the Chrono Trigger one. I like others too, but those are probably my favorite^^; (Well, Brawl's is probably like, way up there, so awesome.)
