Absolutely.  I definitely am an audiophile.  I must have music with me at all times. And I always have been quite fond of video game music.  However, I wish they'd put more effort into them.  A game I always enjoyed on the PS3 for how it integrated music (in fact, it is music oriented) is called Everyday Shooter.  It is like asteroids, and you have to figure out what the pattern is that allows for bonus points, since each level has a different way of giving bonus points.  The level lasts as long as the song that plays for the level.  When you shoot, it adds certain notes to the song, and when you kill an enemy, it adds its own sound to the music.   Also, fl0w has no music, but based on your movements and such, it forms its own "music" by a combination of different noises, even though you probably wouldn't classify it as music.  It still has its own auditory uniqueness that is enjoyable in its own way.  

However, I'd like to see more unique techniques used in actual retail games, and not just shooter type games that add notes and such to the musical score, since that is all I can recall at the moment.
