Fans of Michael Jackson were well aware the iconic artist battled a number of personal demons until his 2009 death. But Jackson’s close friend and legendary producer Quincy Jones disclosed one of the musician’s lesser-known vices.

During an interview with Vulture, Jones admitted there was an unseemly history behind some of Jackson’s music.

“I hate to get into this publicly, but Michael stole a lot of stuff,” he said when asked what the public may not have understood about his late friend. “He stole a lot of songs. [Donna Summer’s] State of Independence and Billie Jean. The notes don’t lie, man. He was as Machiavellian as they come.”

“Greedy, man. Greedy,” Jones continued after being asked to expound on the statement. “‘Don’t Stop ’Til You Get Enough’ — Greg Phillinganes wrote the c section. Michael should’ve given him 10 percent of the song. Wouldn’t do it.”

Jones also weighed in on the personal batter that would eventually take Jackson’s life.

“At the end Michael’s problem was Propofol and that problem affects everyone — doesn’t matter if you’re famous,” the 84-year-old said. “Big Pharma making OxyContin and all that shit is a serious thing. I was around the White House for eight years with the Clintons, and I’d learn about how much influence Big Pharma has. It’s no joke.”
