You guys have to check it out, it's amazing!
It's a fanmade album featuring remixes from the Sonic the Hedgehog 3 and Sonic and Knuckles videogames for the genesis. If you are a hardcore fan like me, you are going to enjoy these remixes.
I'll post my favorite song from the album once I find it. They're all pretty amazing, all the songs are done in different styles, such as jazz, rock, classical, and electronic. Here's one done in metal: The Doomsday Zone. This one seems fairly popular.
