It was a good, solid performance.. IDK if she has range because she doesn't need to to sing that song, its a really simple song to sing like most of the pop songs on the radio now which is what they want, they want you to be able to sing along with them easily. Anyone who says it was flat is not correct, she was exactly were she needed to be for that song. One of her better performances, she has steadily improved each performance over the last 2 months that I have seen ( because there were times i've cringed during some of her performances). Good job Keri
