Gonna have to go again with DoDonPachi. It might as well just be it's own fucking radio station. It has so many damn soundtracks that have penetrated so many genres including rock, trance, techno, chiptune, dupstep, and even jazz at some points. But DoDonPachi 4 Black Label...my favorite.
Then comes Mirror's Edge and the Solar Fields score. That was some euphoric goodness.

I was actually thinking about this previously when I realised how much of an integral part music is when it comes to videogames for me. There are a load of pretty average games that I would have put down ages ago if it wasn't for the music. Hell, the reason why it's such a joy to blast through metal slug 3 so many times is because of the kick-ass soundtrack. In fact, I'd say about 50% of my iTunes library was made up entirely of videogame soundtracks
jet set radio future: amazing game both gameplay and soundtrack. need for speed hot pursuit 2: good game all round really. good gameplay and music. they came togeter really well.
to be honest there is alot of games ive liked for there soundtrack but none of them are really coming to mind straight off the bat. so i'll stick with jet set radio future. i think most would agree with that choice.
some other games that are coming to mind at this point are need for speed underground and halo 2. however i dont remember the soundtracks well enough to add them to my suggestions.
Deus Ex Human Revolution, it fits the cyberpunk mood to the game:[link] Borderlands 2 mixes in redneck, furturistic, a bit of dubstep, and rock into it's soundtrack:[link][link][link] The Binding of Issac and it's expansion pack has intresting music:[link][link] The Darkness has some badass metal going on: [link] Killer7 has some crazy, heroic music. Especially this one:[link]
-Sonic 2(every single zone) & Sonic Adventure -Super Mario World -FF13 -Legacy of Goku 2 -the best of all : LOZ Windwaker (I used to walk around Windfall Island with the game already beaten just to hear the music.)
Tyrian, the game itself is awesome and the music is the icing on the cake, it fits the mood perfectly and gets you so pumped up; it still has that 90s style 'this is videogame music' feel that most games today lack.
the Silent Hill series, Akira is a great artist, though Daniel Licht did a great job in Downpour as well. Heavy Rain wouldn't be the same with out its orchestra. Halo does have good music i cannot lie. The Zelda games always has nice tunes. I like the music in Dragon Age. I enjoyed the sound they had for The Suffering.
Yeah, it's interesting how the Mother series really requires that you play the game in order to truly "get" the music. Earthbound's like that too, though I'm actually not really a big fan of that soundtrack.
Xenogears' soundtrack is one of the best ever, imo. Personally, I'm rather fond of June Mermaid and Flight.
