Amy Winehouse vs. Mark Ronson

Amy Winehouse vs. Mark Ronson
Before Amy left us way too soon last year she and producer Mark Ronson were enmeshed in a very public spat. At the heart of it was the fact that Ronson had built a career on the back of Amy's phenomenally successful 'Back to Black.' Amy started a war of tweets when she said "Ronson you’re dead to me; one album I write an you take half the credit – make a career out of it? Don’t think so BRUV."
