Song of the week: Jessie J's 'Burnin' Up'

Bang Bang, Jessie J's collaboration with Ariana Grande and Nicki Minaj, reintroduced this powerhouse British singer to American audiences earlier this summer.

Burnin' Up, the second single from her album Sweet Talker, due Oct. 14, is a sweaty dance-floor anthem that should further establish her on both sides of the Atlantic.

J belts the song like a disco diva, though the midsection rap from 2 Chainz sounds as if he brought his clogging shoes to the recording session.
