That's because their award system is totally flawed, in which world Justin Bieber is the top artist?
And no shade to Beyoncé but why was she even nominated? Ok, she released 'End Of Time' this year but it flopped and got only into the Bubbling Under Hot 100 Singles.
Just checked again, artist of the year, favorite pop/rock album Justin Bieber? What? I don't even hate him but in which world?
The nominations are so shallow, who actually care are just the kids who vote for Bieber. And no, no matter how much you hype him he will not be the next Michael Jackson.
