I have a theory about Nier (in the Gestalt flavor, at least): Square Enix and Cavia had to decide between making the game visually attractive or making it sound like a heavenly cacophony. They decided this fate with a simple coin toss. Heads - it would be visually stunning, Tails - it would be an auditory orgy of sonic goodness the likes of which no video game has ever been subjected to. If you've heard any of Nier's two-disk soundtrack, you already know how that coin toss ended.
I could sit here and type out how awesome-awesome-awesome I think this soundtrack really is or you could just click on the youtube vids below and decide for yourself (while Youtube allows it). note:
Dtoid's bbcoder is giving me the usual 'Assertion failed: bad pk' error...so it'll just be links to youtube. Sorry! >_<
