Check this out: http://ff7.ocremix.org/tracks/
A compilation of remixes of prominent tracks from the Final Fantasy VII soundtrack. I think they're awesome (albeit a little overdone)

I am working on an adaption of VII's story into a screenplay at the moment. I might have to ask these guys' permission to use some tracks if it ever comes to animating it..

I'm serious, dudes and dudettes.

Listen to this. There's some real treasures in there, even if you're not fan of the OST.

I'll stick to The Black Mages' rock/metal arrangements, thanks.

I've heard some of these before, some of the remixes are good, but I don't think they're better than the original songs.

Good luck with your screenplay, that sounds quite interesting.
