Really awesome.
Regarding Skyduckzard... There has been once a tool called S2MP3, that allowed players of Sonic 2 to play the game, but this program replaced the built-in music by mp3s of your choice. The developers once said they would develop one for Sonic 3 & Knux as well. I don't know if they did complete it, but if they did, then I'm picking this song for Icecap Act2, totally!
Either way, I'm still downloading this song. This is a piece of awesome. I haven't heard Breaktrance in a while and due to my sudden need to listen Icecap remixes once again (I've been hearing a lot of them, and I mean it, a LOT), and I know when I see something good. This gets my fifen and this gets a download. =)
