James Blunt's debut album "Back To Bedlam" is the biggest U.K. seller of the decade. LONDON (Billboard) - James Blunt's debut album "Back To Bedlam" is the biggest U.K. seller of the decade, according to the Official Charts Company.

Dido's debut "No Angel" and Amy Winehouse's Grammy-winning smash "Back to Black" followed. Dido also made No. 7 with "Life For Rent."

Leona Lewis' debut "Spirit" came in at No. 4, ahead of David Gray's 1998 release "White Ladder.

Rounding out the list were the Beatles' "1" at No. 6, Coldplay's "A Rush Of Blood To The Head" at No. 8, the Scissor Sisters' self-titled debut at No. 9, and Take That's "Beautiful World" at No. 10.

Blunt's "Back To Bedlam" did not reach the U.K. albums chart when it was first released in 2004 -- it sold just 482 copies in its first week. It eventually charted thanks to heavy radio rotation for the single "You're Beautiful," and ended up selling more than 3.1 million copies.
