The problem here is she doesn't have a live band or backup singers. Britney Spears sings with a backing track so you hear her a little, she's not fully lip syncing. The only thing on the track however is britneys voice. On stage you have the live band and the backup singers. It makes it seem WAY more legit. Here everything on track so it just sounds just like they're playing the CD. She either didn't have the funds for the band or she has really bad organizers who didn't do their job.
