What video game OST caught your ears?

Let me clarify the title's question.

What video game original soundtrack made you first realize that music put into video games wasn't just for farts and giggles, but was used to invoke real emotion like making you care about the situation on the screen, provide a spine-chilling atmosphere, create an intense competitive moment, or simply provide a charming jingle?

For me it was the theme for Bowser's Castle in Super Mario Bros. for the NES. Creepy music for a creepy place. I mean for a 5 year old with weak constitutions it made my damn hands shake on the controls, haha.

So yeah. What's everyone's story?

ODST ? yeah man I can't wait !!

I dont really remember to be honest. I find it hard to remember specific music from anything but the most recent games I play.

Ocarina of Time.
 
So many memorable tunes.

I love the music from YS: The Oath in Felghana. And of course most Mega Man and Castlevania games. I used to listen to the intro in Mega Man 3 every time i played it as a kid.

Legend of Zelda: Oracle of Seasons/Ages is the first one that made me realize how awesome some of the music was.

Megaman....
 

I can't think of the first OST that made me realise that, but Grim Fandango's is one of my favourites!

The first video game OST that caught my ears was that of the first game I ever played... Super Mario Land for the Game Boy. The OST in that game was just perfect... especially the song that played during the credits. Gave me the chills back then, and it still does.

I don't often notice music unfortunately. But most recently I can remember liking Valkyria Chronicles music a lot. But the FIRST game would probably have to be Super Mario Bros. No game's music has ever stuck in the ol' brain like those tunes. 

Definitely whatever the first Zelda game I ever played....A LInk to the Past I believe? Ocarina of Time as well. Also, I remember Goldeneye's soundtrack being surprisingly awesome.

Probably around the release of Final Fantasy VII or VIII. I always thought the Final Fantasy series had fantastic orchestration.

Chrono Trigger was probably the first one that caught me as a kid. I love the music from that game. Particularly the main theme.

I loved the soundtrack to Splinter Cell: Chaos Theory. Amon Tobin is a genius.

Bully, InFAMOUS, FF8, BOF 3 and Shatter.

Chrono Trigger and Donkey Kong Country 2.

Fable tlc's, mass effect, oblivion's music

A Link to the Past or Secret of Mana, because I recorded some of their soundtracks onto a tape as a kid. I just found that tape the other day!
 
Now I collect game music CDs, with way over 300. But I owe it to that first tape.

One soundtrack which it seemed like NO ONE talked about was the soundtrack for Bully, which I thought was fantastic.

Halo, it is the only game that i got shiver hearing that theme song for the first time.

Megaman and Link to the Past. So many memories.

I own the Phantom Brave soundtrack. 
 
That's mostly because NIS sent it to me when they had sent a review copy of Phantom Brave. 
 
I don't really listen to it.

Super Mario Bros. has some of the most memorable music in all of video gaming and was prbably the first music I really remembered from a game.  I remember my dad made me turn the sound off on the TV because he couldn't get the music out of his head.

Megaman 3. I never had Megaman 2 but everyone seems to cream over that one. It wasn't until high school that I played megaman 2.

One of the first was Super Mario Bros.
 
After that, it's probably Final Fantasy VII

Pretty much the entire Final Fantasy series (Uematsu, I think is the guy's name? love is his stuff). Most recently though, Castle Crashers. I love the sound of that game.

The entire Donkey Kong Country series is incredible, but in my opinion DKC2 is the best of them all. Dave Wise did things I didn't know were possible on the SNES. As great as the gameplay and graphics are, the music really set it apart as one of my favorite games ever.

The PC version of Jurassic Park.  No joke.

Final Fantasy 7

" The entire Donkey Kong Country series is incredible, but in my opinion DKC2 is the best of them all. Dave Wise did things I didn't know were possible on the SNES. As great as the gameplay and graphics are, the music really set it apart as one of my favorite games ever. "

I'm not sure. My memory of that stuff is a little foggy, so I'll just have to go with Metal Gear Solid. 4 did it especially.

ne god of war song

Shadow of the Colossus
Mega Man 1-6
Mega Man X-X6
God of War 1-2
All Metal Gear Solid Games
Chrono Trigger

The Orange Box OST is the only video game soundtrack on my iPod, I love the TF2 music

World of Goo has some of my favorite music from any videogame.

I own that OST, along with...   

My Favorites-
FFVI 
FFVII 
Zelda: OOT  
Braid  

Others:
Super Mario Galaxy (Not my favorite, but a few songs are nice) 
Age of Empires (Just for nostalgia, really) 
Zelda: Wind Waker (Same as SMG) 
Afro Samurai (Underrated game IMO, I had alot of fun playing it. Decent soundtrack)
Dawn of War 2 (It was free)     

All the Panzer Dragoon games' sound tracks. From the first one's epic orchestrated pieces to Zwei's organic tunes to Saga's Ecce Valde Generous Ale, to Orta's vocalised Anu Orta Veriya, they're all pure bliss with an incrredible variety of styles. Some random samples, look up more even if these particular tracks aren't your thing, as especially Zwei and Saga have many vastly different sounds to their tracks.
 

The Silent Hill games!  
 

Forgot one in my last post, and accidentally put the instrumental version of a song there, this is the normal one.

Bully and Kingdom Hearts II

Quite a few zelda's would have... if they weren't MIDI! Christ it's like listening to the music in pokemon gold for the gameboy color.

Metal Gear Solid is the first game I can remember where the music's stuck with me, I loved that game so much when I was a kid.
