Amy Winehouse and Mark Ronson are slated to record a song for Quincy Jones’ upcoming tribute album. Joining a roster that already includes Usher, John Mayer, and Mariah Carey, Winehouse has signed on to record with Mark Ronson. “It’s going to be explosive stuff,” a source said. “He knew who she was and she was so thrilled to meet him. Her performance clearly impressed him – he was raving about her. This is just the opportunity she needs to show the world she has still got it.” In related news, Amy Winehouse has been rumored to be struggling with the follow up to her Grammy Award-winning album “Back To Black.” “If six months produces two half-baked tracks, how long will an album take? Unless she sorts herself out and gets some focus it might never happen” a source told the Sun.
