Label: EMI
Key Track: "LDN"

Barely a singer and definitely not a rapper, Lily Allen was utterly unique when she burst on the scene with Mark Ronson's poppy, mod-hop beats and her infectious, funny sing-songy flows about all the fun things bad girls like to do. Yeah, it's a guilty pleasure for dudes, but we're not afraid to admit it: Lily = the trifey we'd wife in a minute.

YOU AUGHTA KNOW:
The album's title references a phrase Allen's brother used for "cool" and was also inspired by the Albert Einstein aphorism: "Nothing changes until something moves."
