As I ambled my geeky way around the internet I came across http://s3k.ocremix.org/.

They've put together an album of reinterpretations of the old Sonic 3 music. It's all there, free for download.

AND IT'S WONDERFUL. My current faves are "Walk on Water", "Malicious Fingers", "Live At The Sandopolis" and "Doomsday". Check this out if you're a big Sonic fan
