I had played this game for 5 mins its just monotonous button pressing to Britney's awful music, for what, Back stage footage of Britney, whoopty doo. The game play has obviously has been stolen from Bust a Move. Overall avoid this game as best as possible.
I loved this game!! It's fun and challenging and I really liked unlocking the backstage and rehearsal footage. The stages you preform on too are much like ones britney would or already has. I would give it a 10 but I found it a little hard and I wish there were more songs on it, but all and all it's a great game.
