Amy Winehouse‘s award winning album ‘Back to Black’ has become the best selling album of the 21st Century just days after the singer’s untimely death.

The musical milestone, which was official announced by Britain’s Official Charts Company, puts winehouse ahead of previous record holder James Blunt, whose 2004 album ‘Back to Bedlam’ held the title for almost six years.

Amy Winehouse was found dead in her West London town house on July 23. An initial post-mortem failed to pinpoint the cause of death, however toxicology reports have subsequently stated that the singer had no illegal substances in her system when she died.

Speculation has moved to legal drugs, with many drawing parallels between winehouse’s death, and the death of Actor Heath Ledger, who had a variety of legally obtained prescription drugs in his system when he died.

Winehouse’s parents are standing by their earlier belief that their daughter died of Alcohol Withdrawals, which kills more people than Cocaine every year.

An official inquest into the ‘Rehab’ singer’s death will begin in October.
