London, Sep 6 - Scottish singing sensation Susan Boyle's debut album has topped the bestsellers list on amazon.com even months ahead of its release.

The singer's album 'I dreamed a dream' will not go on sale until Nov 23, but thousands of copies have already been sold to fans who placed early orders on the shopping website, reports thesun.co.uk.

The CD is even outselling American artist Whitney Houston's comeback album as well as other pre-release titles such as the 'Twilight' soundtrack.

The album features a cover version of Madonna's 1995 hit 'You'll see', which the 58-year-old insisted was part of her debut.
