Here's my list of games with soundtracks I think just kick you-know-what.
Left 4 Dead 2: It's got banjos. It's dark. It's brooding. For atmospherics and scene setting, it cannot be beaten. It's brilliant. It's even my ringtone. If you play Left 4 Dead 2, the 'saferoom' music is my ringtone (I also have 'the tank' music for my ex-wife). I've even done a template here based on it.
Command & Conquer: Pretty much anything by Frank Klepacki gets my vote. Awesome soundtracks.
Quake 2: I just love the industrial metal tracks of this version of the game.
Inferno (old '90s PC game, sorry): Alien Sex Fiend blowing my socks off.
Yeah, I'm showing my age. What floats your boat?
Games music is a quite cool "genre",
I remember being positively surprised about the quality of blues tracks used in RailroadTycoonII :)
A project showing real love for arcade game music is the one shown in below youtube video:
These guys perform the full soundtrack to the game Megaman 2 as one guy plays the game live on the stage.
Quite the watch, I guess it doesn't get nerdier than that:
yes, you are looking at the administrators signature.
I got my dad to teach me how to play the Maple Leaf Rag on the piano because I heard the C64 version of it on China Miner!
"My guitar sat in a corner. Then I discovered wikiloops and now, not one day has gone by that I haven't played it."
