I thought it was well known that Deadmau5 is a bit of a dick lol. Like a geeky john mayer, he’s an ass but the people love him, Like it’s been said both are at fault here, Deadmau5 had no right asking the DJ to completely change up his music nor was his tweet, about how much the music sucked, justified..but that sure as hell doesn’t justify punching him in the back of the head unless more was exchanged between the too. Like it’s been said, we may never know the whole story.
