US producer Mark Ronson is convinced British singer Amy Winehouse will be a huge success in the US because her music and style are so unique. Ronson, who worked with the REHAB star on her latest album BACK TO BLACK, was blown away by her vocal talent and insists Winehouse is far better than US stars like Britney Spears and Christina Aguilera. He says, "I think the thing is traditionally, 'black music' like hip-hop and soul music, it's always been hard because that stuff comes from America even though there's a lot of talented English artists that do it, so, (the US is) always a bit sceptical. "But the Amy stuff is just so good and just so refreshingly honest and raw and pure and obviously she's written some great songs and she's interesting to read about because she says honest things."
