Sugababes have to be the hardest—or at least fastest—working girls in pop at the moment, considering that, with the exception of 2001 and 2004, they've had a new release out each fall since 2000.
Granted, one of those was a greatest hits, but they also re-recorded parts of 2005's Taller In More Ways for its '06 re-release once Mutya Buena rolled.
And thank God these broads found decent stylists to work with. They looked like three transexual tweens hookin' at the playground back then.
