My Name Is Kay, which in the chorus reminds me of the Ting Tings but she is infinitely better than them. She's also not a cliche rapping thing like a lot of other wannabe's and her mixing of genre's is great.
Cory Lee. I'm not going to even bother to pick out a song. She's that good. There isn't too much there, but Best Shot is my recommendation. She's bouncy and while not the most original, it's good.
