(AllHipHop News) English producer Mark Ronson has one of the biggest hits of 2015 with “Uptown Funk” featuring Bruno Mars. Ronson actually debuted the worldwide #1 single on Sway In The Morning, and he returned to the Shade 45 radio show to share some stories and thoughts on other music stars he has worked with during his career.

One of those performers was Jay Z. According to Ronson, he spoke to the Hip Hop legend during a deejaying gig for the The Dynasty: Roc La Familia release party in 2000.

“Jay comes up to me – and I don’t really know him that well. I thought he was definitely going to say, ‘Can you please never use one of my f*cking parties to hype up your record? Go back to playing some Roc-A-Fella,’” stated Ronson. “He says, ‘You did that beat right? When you do a remix, let me rhyme over it.’”

Apparently, Jay never returned Mark’s phone calls about the possible collaboration. But Ronson did get to work with Amy Winehouse. In fact, he played a big role in the late singer’s classic 2006 album Back To Black. The Brit Award winner was asked about the critically acclaimed documentary Amy which covered the rise and fall of the troubled artist.

“I think most people know the music’s pretty great, because when it came out it was really the thing that made people pay so much attention [to Winehouse],” said Ronson. “But toward the end, I think everyone might have forgot it, because everything became so much about the more ‘tabloidy’ stuff.”

He added, “She was a proper lyricist, and you see that in the film. It puts her back up on a pedestal. That’s what the director [Asif Kapadia] was saying. You remember she’s a f*cking brilliant talent.”
