Eh, haters gonna hate. Skrillex is good, and imo has changed EDM scene for the better.
Before him dubstep was.. Too mellow, I mean they still make it, but the dubstep you hear today is more dancy. And considering I prefer House, I like it better this way. Drumstep, DnB, Electro House, Dubstep, all progressed so much recently, and a lot had to do with people like him. He's inspired a lot of people.
