I find that video game music often goes unappreciated in music discussions, so here's the place to share your favorite songs. If you're going to post links, for the sake of people actually listening to some of what you post, please don't post more than... four.

Mother 3- Happy Town? http://www.youtube.com/watch?v=C-P1HnqR ... re=related

Mother 3- 16 Melodies http://www.youtube.com/watch?v=UZbqrZJ9 ... re=related

Digimon World- Gear Savanna http://www.youtube.com/watch?v=aLJWjie6P8g

Resident Evil Outbreak- Main Theme http://www.youtube.com/watch?v=Vc671bo3fbw

Honorable mentions go to every other song from the Mother series, the piano theme from Silent Hill 2, MGS4 Love Theme, and Scrap Brain Zone from Sonic the Hedgehog.

I think I can go on with for awhile if I can remember the songs in each game I've played. I will post four from games I can immediately recall:

Final Fantasy XII: Ozmone Plains

Yu-Gi-Oh: Duelists of the Roses: Vs Lancastrians

Pokemon Gold/Silver: Goldenrod City

Resident Evil Outbreak: Umbrella | This song goes very well with the cutscene it is played with.

Yeah, Umbrella is a great song. I used to be that guy who doesn't skip the cutscenes just so I could listen to this, and The Extermination. That Yu-Gi-Oh song is interesting, I like the strange combo of instruments.

Honorable Pokemon mention: Uxie/Azelf/Mesprit Battle | Good battle song.

Spyro 2 Ripto's Rage: Colossus | Hilarious.

I like a lot of songs in Earthbound, but it's been awhile since I've played it.

DMC3: Devils Never Cry
Halo 2: Halo 2 Rock theme
Fallout 3: I don't won't to set the world on fire.

End Credits BGM - Outbreak # 2
Never Surrender - Devil May Cry 4 Theme
Zelda Ocarina of Time End Music
Duke Nukem Theme Music
RAYMAN 2 Theme Music
RESIDENT EVIL 1 Save Room Music

NOSTALGIA

For me its every song from both Jet Set Radios, Bionic Commando Rearmed and Sonic Unleashed(EXCEPT FUCK THE WEREHOG BATTLE MUSIC, it interupts some really great songs incessantly.)

EDIT: Some examples I guess.
