29. Deadmau5, '4x4=12' (Ultra Math, 2011)
He may suck at math, but Canadian EDM superstar Joel Zimmerman is definitely more than just a happy dude bouncing around in an LED mouse hat. His fifth and best album shows off his ability to stretch his signature good-mood progressive house in a number of directions – from the speedy groove and OCD car-alarm melody of "Bad Selection" to the thick Daft Punk-like vocoder-funk of "Animal Rights." "Raise Your Weapon" is a quintessential Deadmau5 anthem: slowly lapping synth waves, a gently triumphal beat and singer Greta Svabo Bech's invitation to "watch it burn," followed by a harsh blast of dervish bass that's hard but not too hard. If Skrillex is Metallica, this guy is Bon Jovi.
