Miley is doing what most 20 year old girls do which is party, twerk, and be a tryhard ratchet. The only thing is she doesn't do it well. She can't twerk and she obviously JUST got hip to black culture and urban music. Bieber his appropriation is a bit more genuine since he grew up listening to hip hop/r&b. Miley bragged about not knowing a Jay Zoo song the other year but now she's like "I listen to urban."
