And what a return it is. Rehab is fresh and funky, with a definite old-school, horn-laden, Motown atmosphere to it. Gone are the jazzy yet edgy ballads of the last album, and unveiled is a sleek, commercial yet very different sort of sound. Winehouse's voice is as terrific as ever - she's been away so long it's easy to forget what a superb singer she is - while the strident chorus of "they tried to make me go to rehab, but I said no, no, no" must surely signal a huge hit.

Last time around she seemed to garner more press attention than commercial success. If Rehab is anything to go by, that is just about to change in a very big way.
