If you're finding fault with THAT song, you really should check out her first "single," a golden leprechaun turd polished to new levels called Friday.
To be honest, it was never meant to be anything more than fun for her and her friends. Her rich parents gave her a present of making her own music video (which is why you have this dumb as a rock rap star inserted right in the middle, apparently it's their studio that offers the service) and it somehow went stupidly, over-the-top, way-out-of-proportion viral. Proof that the masses have de-evolved to useless, brain-dead sheep with no idea of what is good or bad. I hear she actually sold over a million copies of the song on iTunes long after it had gone bonkers on YouBoob.
That said, she HAS improved tremendously, but still not my style to listen to.
