Let's be 100% real Christina is not the best singer but sounds way better than Rihanna. The problem is she's kind of lame and doesn't stand out in a crowd of singers. Rihanna got the pop audience and she took a rocker(fe-fe dobson) style and a pop & r&b(kelis) haircut 2 fairly unknown artist in each others demographic music groups and ran with there styles unbeknown to a lot of folks. That being said she was probably dropped for Rihanna it isn't fair but it sometimes happens. So this time I say come harder this won't be easy don't doubt yourself in the words of Bey. Christina prove them wrong because Rihanna doesn't have that much longer herself.
