The Amplifier says it better than I could. From the article:

[Amy Winehouse's "Back To Black"] has officially been named Britain's best-selling album of the century. A few notes:

“¢ The century is really not that old yet.

“¢ Winehouse has saved Brits from a load of embarrassment: The previous top-selling album of the century was James Blunt's 2004 disc Back to Bedlam, which featured his ubiquitous, irritating smash "You're Beautiful."

“¢ Everyone in the U.K. should go buy a few more copies of Back to Black to ensure Back to Bedlam doesn't sneak back up on it because the margin is pretty slim -- 3,259,100 copies of Black compared to 3,241,118 of Bedlam.
