It's not about finding some one arsed enough to spend that time doing so, it simply won't happen. There've been a few threads before suggesting similar ideas and all were met with a big, fat, no; not without good reason.
Just trying to save you the trouble and time you could have spent better upon. Like trying to beat my highscores on Gradius V or something.
Edit*
Why pigeon hole all the tracks into genres when they can all be a surprise when you listen to them..?
At the very least, all the tracks have an opportunity to entertain some one who'd not likely hear it in the first place had it been plopped into a genre section.
However, certain games often get certain types of music, or at least most recognizable. Final Fantasy often get classical and rock, Megaman rock and some metal with electronica ect.
