Released a while back was an interesting remix/mash up album taking the disparate musical worlds of Nine Inch Nails and Final Fantasy and throwing them together in an intriguing and new way. The album is a free download from the artist Cody Walton AKA HALO_ZERO and can be found at ff7z.halo0.com. A definite download for anyone who likes either one or both NIN and FF7.

Also have to mention that it is heartily endorsed by Hex of Nerdapalooza fame.
