In reply to Coolness.

You hit the nail on the head.., the previous crop of popstars; Britney, NSync, Christina, P!nk etc. really had to work for their supper to compete with the cooler RnB, Hiphop and Rock stars of the time. Pop performers really weren't taken seriously at that point so they had to work for it and that's why they each knew how to slay the stage during their post-teenage peak. The current crop of popstars are generally quite lazy in comparison.
