By Celestia! Dvixer sent in a truly impressive pony music project he's completed. He worked out the instrumental lines for the Cutie Mark Crusaders Theme, then mixed it back together with the original pony vocals. It's so well done, he had to promise it wasn't faked in any way. It's really as good as it seems.
Watch the video to see it for yourself, or download the m4a file. Then visit Dvixer's Youtube channel and give him a well-deserved thumbs-up.
