Girls Aloud's first track was fantastic, a really fresh and exciting new sound and this track takes that idea and creates a track that is amazingly even better. the track plays a funky guitar and drum riff with some ballsy vocals that manage to be aggressive but still impress the listener with their range. The girl's voices all blend together brillantly and the chorus is brilliant. i'm not the kind to buy singles much but i am most definitely getting this and the subsequent album. this is an essential purchase
