Justin Bieber broke the rules and went on to diss his own mentor Usher during a recent interview with Complex Canada. Bieber said he was finally doing dance music the correct way, which Usher failed to do.
“I have these collaborations with Skrillex and Diplo, like 'Where Are U Now' that just took off. This is their first top 10 record. It just shows that we’re breaking barriers in the EDM world. I think people have been trying to do it for a while, making dance music, like Usher and all of those people, but I don’t think it’s been done in the right way.” So ungrateful (wouldn't be the first) and conceited that he would publicly say this about the man who took him under his wing and helped him get his first record deal. I can think of several things to describe JB's music and the words "genius" and "breaking barriers" simply isn't one of them.
