Just to point out...
Your song is released in under a Creative Commons License (CC BY-NC-SA 3.0, to be specific). This means if he does not attribute you, or uses your property commercially without your express permission, he is in violation of the license you released your song under. Do also keep in mind, if DJ S3RL holds copyright on Pretty Rave Girl (which I presume he does), you may or may not have grounds to sue this DJ Ezio.
Outside of that, I really enjoyed this. I've always liked this song, and I feel this cover does it more than justice.
