Jordin sang it live all the way throughout, though there were times she sang just as she sang on the backing track, making it appear as if she were lip-synching. It's ridiculously common these days. I'd have preferred to have back-up singers, instead of a backing track. that would have made it seem less like they were just playing the single and singing on top of it.

And, yes, Jordin > any S7 girl.
