Label credits media interest for Winehouse success

Amy Winehouse's record label has put the success of her hit album 'Back to Black' down to the increased media frenzy surrounding the singer's turbulent personal life.

The Rehab star's sophomore album was named the world's biggest-selling record from a British artist in 2007, shifting more than 3.4 million albums across the globe for Winehouse's record label Universal Music International.
