There are actually concerts for bands or orchestras who do game music.
I like all kinds of stuff, usually music in a game makes it more interesting. Unreal Tournamet 99 music was indeed really cool to listen to, they made the songs fit the maps ambience.
I also like WoW music, greatly done.
For the most part i like most Game songs, except for the ones that put the game out of it's style.
Kind of like how shit isn't a good combo with Strawberry icecream.
