We've said it before, we'll say it again.... Deadmau5 is truly the master of trolling. He recently performed at Glastonbury Music Festival, where he proceeded to play his track “Seeya” before exiting the DJ booth, kicking back on a sofa on stage and drinking Coronas with Left Shark. Now, following his Twitter rant on the popular Jack U collaboration with Justin Bieber, "Where Are U Now," he has released his own version of the track. It’s antics like these that have made Deadmau5 one of the most talked about figures in the scene. Listen to his remix of "Where Are U Now" above.
