Well, top two are Ciara and Lil Kim. I don't find Ciara or her music interesting. And there's the whole Twitter mess with Rihanna that didn't help my opinion of him at all. Lil Kim is ****ing Lil Kim and I do not need to explain any further.
Then there's Keri Hilson and Natalia Kills. Keri... she's her own. I find her incredibly basic, but I do have to admit that I do find myself jamming out to Lose Control and Toy Soldier on occasion.

And Natalia, even with decent music, is incredibly delusional and generally obnoxious.
There are artists I don't necessarily like, but those 4 just are those that automatically stood out.
