Nicki.....
I know she's been getting a lot of hate, but she fell off really quickly (ever since Your Love became a hit I lost all hope) and people still loved a lot of the stuff after....
I just hate her pop music, and not because she's selling out, because it's really, really, bad.
Just because your fave didn't make the list doesn't mean she's not overrated as well, the only thing she's really got is her voice and even that is weak and strainy at times. Just because you're a flop doesn't mean you can't be overrated.
