Brit Award Nominee: Jessie J

Nominee and winner of the Critics Choice award, Jessie J has a powerhouse voice comparable to Jazmine Sullivan. I shouldn't compare people, but they both are great at controlling the power behind their voices. They use the power to emphasize and not just because they can. These British women are seriously coming for the Americans. Watch her stun gatherers into silence with her live performance of "Who You Are" at the Times Square subway station in NYC.
