In my personal opinion, I think the music in this game is absolutely incredible. Its beautiful, it's smooth and just nice. I will sometimes leave the game on the main menu, turn on the stereo, and walk around the house cleaning up or read my book just to the music. Even some of the in-game music is badass, such as the final story mission where you're fighting all those Hive, the music pretty much makes you feel like a badass if you play it on hard. But all in all, will Bungie be releasing a soundtrack? I would assume they would, but I just wanted to implement and hope that certain tracks will get in there. I'd buy it in a heartbeat. Thanks Bungie for making this amazing game though, I'm on the edge of my seat every time I play it!! Look forward to playing it on release!
