16-bit Game OST's?

I'd love to have the entirety of the oldskool Sonic the Hedgehog soundtracks.  Not remixes from like ocremix, but the real soundtracks.  I have a couple from some levels and I don't remember where I got them.  Is there a complete torrent for this kind of thing?  Not limited to Sonic, of course.  All the old synthesized 16-bit era music is awesome.  Sonic is, of course, my favorite.

yes, okay, ocremix is for fuckfaces.  I know.  That's why I said I wanted to avoid it.  Now, where should I get 16bit OSTs.
