Someone explain Justin Bieber to me please

OK...so he's a "superstar"...yet I don't know any of his songs (and still ponder whether or not I'm using the right pronoun). Someone explain his success to me please! He's got kind of a wimpy, nerdy body. He's not exactly handsome...in fact he's the polar opposite! He's prettier than his female fans! Oh, sure...Usher sort of discovered him...but Usher still hasn't discovered talent or artistry (my opinion, and I'm sticking with it). Oh, how I wish I could write an Usher song! Oh, wait...I can!!!  "Yeah....yeah...yeah...yeah"! There...that's a #1 hit for some totally unknown reason! And Usher isn't even really good looking. Someone explain his success to me please! I guess the youth of today just doesn't have the appreciation of lyrics, musical talent, or artistic merit anymore. Yeah, I'm sounding like my mother's generation...but SERIOUSLY?!?!?!? Have you listened to 90% of the "music" crap that's being fed to the younger generation? I could go on, but it's after 11pm and I need to get up for work in the morning. Yeah, I'm old!  LOL
