Cheryl Cole (Polydor)

From X Factor winner to X Factor judge – but who comes out on top? In truth, neither of them. The fizz that brought many of the Girls Aloud singles alive is absent from tracks such as Heaven and previous single Heartbreaker, thanks in no small part to the mediocre songs and production delivered by the apparently unavoidable Will.I.Am. But while Burke at least has her strident voice in her favour, Cole is really no kind of a singer. Unengaging.
