The Saturdays - Work

In less than a year since The Saturdays released their debut single, they've gone from fledgling newcomer status and destined to be labelled as a second rate Girls Aloud for the rest of their career, to one of the UK's best girl bands.

'Work' is exactly why the five-piece have notched up a string of top 5 hits and are currently on a sold-out tour of the UK. Just as the accompanying music video shows five pouty and uber-confident girls - 'Work' is an upfront sexy R&B dancefloor filler - heavy on the synths, even heavier on the beats and featuring the sassiest vocals we've heard yet from the quintet.

Compared to slower songs like 'Issues', it's this high-energy and maturer dance factor where the girls are in their prime. If their second album is crammed with songs like this, it won't be long before they are selling out arenas.
