Honestly? Don't like him, and here's why;
1. Music; Simple, I don't like Pop music. I like bands like Four Year Strong, The Used, Bullet For My Valentine, etc.
2. His fans hyping him up; point? Their treating him like he's some sort of a god, when the truth is he's just a white kid [let's be honest.] from Canada. Then when you tell one of his "Bielebers" [seriously...] you don't like him, they hit out with "OMG YOU'RE JUST JEALOUS!" No I'm not, shut up.
3. How much he's being shoved down our throats; Because he's been picked up by Usher, he has to be shoved down our throats? He's only 16/17 or something and he's getting a movie about how he rose to fame? Genuine WTF moment there.
And that's why.
