Which games have the most recognisable/iconic soundtrack/theme?

Deus Ex?
X-Com (especially new Enemy Unknown and Enemy Within)?
And old jagged alliance 2 and all Fallout series

A number of games in this

Gothic 1, Crysis 2 ,etc.

Here's all I can remember right now:

Portal 2
To the Moon
Mafia II
Grand Theft Auto San Andreas and Vice City
Bully
Need for Speed: Most Wanted (2005)
Resident Evil 4

Maybe the last four games' soundtracks are the most recognizable for me because I played them a lot of times on the PS2.

my list: Total Annihilation, Mechwarrior 2, Earth 2140, Quake, Doom, Duke Nukem 3D, The Impossible Game, Super Meat Boy

This.

Need For Speed Underground 1 :D
PeteyPablo-NeedForSpeed :X
Need For Speed Hot Pursuit 2 ( first one,older one ),this song :X - HotAktionCop-FeverForTheFlava

Thomas was Alone is pretty good in that aspect

and definitely don't forget Minecraft, I mean, if you haven't you should go listen to the game it really makes you feel

Well I know if I heard skullgirls music, i'd be able to recognize it straight-away. They put a lot of work into their tunes.

Let's see, I don't know how Etrian Odyssey's new orchestral sets will turn out to be very recognizable. but Etrian Odysseys 1-3 had very distinguishable soundtracks.

I also hope mah new babi will have very recognizable tracks <:'D some of those themes are awesome. And the boss theme is da best. <3

Chrono trigger, Monkey Island Series, Toe jam & earl, Sonic, Mario

Super Mario bro's

Tetris

Every single Touhou game,though 06 to 09 are probably the most iconic.

Crash Bandicoot trilogy;)

definitely assassin's creed II: Ezio's family

Dark Souls

Street Fighter ( Guile's Theme)

Rocketbirds: Hardboiled Chicken - honestly

Splash Wave

Zelda series ... but like you said, most Nintendo games have a very recognizable theme (and Tetris / Supoer Mario were already mentioned).
