What's your favorite Video Game Music Track?

I recently just finished a video compiling my top 20 snes songs of all time, In video form.  It's two parts, it took me quite a while, but it was a lot of fun. It got me thinking how much more music I should have on my hard drive that I just don't. 
 
So my question is, what is your favorite piece of music from a video game?
 
Here is my video if you guys are interested:

Nice work with your videos!
 
Video game music is actually some of my favorite to listen to. I really could honestly not pick a favorite song, but I'll share a few of my top favorite soundtracks.
 
Final Fantasy

• I really like all of that music in general...
• The Piano Collections by Nobuo Uematsu are awesome, check them out if you haven't.
  
• Black Mages I and II. Great rock versions of the best FF themes.

• Halo 2 had an awesome soundtrack, in my opinion. Listened to that one for a really long time.
• Peril is one of my favorites on the soundtrack.
  

• One word. Nostalgia.

• Obvious favorites are popular themes from Mario, Metroid, and Donkey games. The Super Smash Bros. soundtracks seems to have a good variety of popular Nintendo themes due to the games nature.

The opening theme music from Final Fantasy 8 which the name escapes me at the moment has always stuck with me as pretty intense and at the time I remember watching that FMV thinking man this game is going to be amazing. And also anytime I hear the Sonic 2 theme  I'm suddenly 6 years old sitting on the living room floor staring up at the TV again.

OR also anyone know some great remix artists? I've been listening to a bunch of Halc recently and he is awesome. 
 
I totally love that FF8 opening to Thrice. 
 
and i've never played Jet Set Radio before, but i think i'll listen to some stuff from it soon.

Probably the main tune from Mutants on C64.

Quite a few of the tracks from Ocarina of Time.
This dude does awesome remakes of them on guitar:
 
  

Vice City Soundtrack: best music ever in a game.

 Lisa Miskovsky - Still Alive in Mirror's Edge or To Zanarkand in FFX.

I absolutely love the battle theme from Final Fantasy IX. 
 
  

I love gaming soundtracks, but to pick a single song...? I personally don't know, really... as of now, nothing pops out as being incredibly better than everything else out there.
Here's some of my favorite soundtracks, though, if you guys want to check it out.

Also, I just have to mention this song: 
 
  

" Vice City Soundtrack: best music ever in a game. "

Battlefield theme, Republic Commando soundtrack, Call of Duty 4 soundtrack, Bionic Commando (newschool) soundtrack.

"   

  I have plenty of favorite soundtracks, Vice City, Bionic Commando, Warcraft and Battlefield being among them. But one of the albums I still listen to is Mass Effect. "

I blame the lack of an equally amazing soundtrack for ME2. "

If I have to choose one it would be To Zanarkand from Final Fantasy X.
