It's not a Deadmau5 song. It's a remix. Every "Deadmau5" tune people have linked to in efforts to defend him has been a collaboration of some sort, i.e. Kaskade + DeadMau5, that remix. I'm yet to see anyone suggest a track that he produced and recorded solo which shows he has anything more than the ability to make mediocre electronic music. The recent stuff could even be classified as a bit pop.
What about this?

) about deadmau...sounds just like another house DJ. I've been to one show and am in no rush to return really. When it comes to live performances there are plenty of other artists I'd rather go rave to.
