So there are 2 basic schools of thought when it comes to covers:
1. keep it as close to the original as you can (hence the moniker "cover")
2. put your own spin on it and take something someone else did, pay tribute to it, but make it your own
I kinda think he was successful at #2. It's not my thing and I wont judge it, but he definitely put his own spin on it.
What the hell do I know. I should really stop posting! LOL
