All I really know about Deadmau5 is that his cover of Rope is a bit lame.

Maybe its just me being a huge fanboy but I feel like that version just gets repetitive and boring after the first verse. It doesn't change at all. It feels like he slowed it way down too.. It's just kinda boring, it's not nearly as exciting.
Edit: Just remembered that this also got a grammy nomination for best remix... Idk if I'd agree with that either, he barely remixed it. The voice track is identical, and the same beat loops throughout the background the entire time.
