It took every living nerve in my body not to use phrases like "tragic mess", "inane twaddle" and "Ye Gods!" when it came time to review The Saturdays' second album Wordshaker, so I'd still be the first person to whine if new track 'Notorious' was more of the same from the rainbow-coloured pop naifs. On the contrary, the first single from their forthcoming third album is smart, edgy and bubbling over with cutting edge pop gimmicks. "I've been a bad girl, I'm a bad girl," they honk in glorious, distorted unison. That may be so, Una Healy and friends - but you know what? Here you've done very, very good.
