Re: Best music in a game?
As far as single tracks go, "Agnus Dei -Megalith-" from Ace Combat 4 is the best music I've ever heard. It's worth playing through the game just to hear that music.
For soundtracks though, I agree that Jesper Kyd is great. Freedom Fighters has one of the best game soundtracks I've heard, and his work on Hitman is pretty good as well. He does some nice techno too (even if it is a bit generic), Scorcher and MDK2 have some really nice techno beats in them. Wonder what his next project is...hope he's making the soundtrack for Freedom Fighters 2.
