It's breakcore. And Deadmau5 is very mainstream electronica these days, hence my comment.

He's really repetative, which is kind of what I like...

I got to see DeadMau5 a couple months ago in Tampa, fucking ridiculous show.

Ridiculous is a good way?
He was at the awards last night. :o

yes as in awesome! I saw that too, he was wearing a shirt with Skrillex's phone number, pretty funny joke I guess. Speaking of which, I just found out Sonny Moore and Skrillex are the same person, I'm retarded.

Derp.
Though to be honest, I find it strange how I've never heard of Deadmau5 until this year, but he's apparently been famous-as-fuck for years.
Just like every celebrity, these days... it's kind of suspicious.
