It's hard to choose as none of them are that good to be perfectly honest, I mean they probably would go down a storm at any working man's club on a saturday night but after this show has finished how soon before the acts are too?It's good entertainment till the next X-factor starts and that's how Simon sees it, he'll squeeze what he can out of this format continually, as it makes him richer and richer but for all these series of PI,X-factor,Popstars,etc how many successful artists will there be? I voted for Cassie by the way, the rest are dire.
