Mark Ronson has defended himself from detractors who are convinced his DJ job is easy, insisting he spends 14 hours a day on his music.
The superproducer has often been criticised for spending so much time at parties but he maintains he actually works - and he's eager to prove them wrong with his new band, The Business Intl.
He tells Britain's Daily Star, "Some people might have seen my lifestyle in magazines and thought, 'Oh, he just DJs at lame celeb parties' but most of the time it is work. It's great work, but still working.
"I spend 14 hours a day doing this s**t, so I mean business. That's how the band came about. There's also something about it being a bunch of serious individuals. On my last album, Version, I was playing most of the instruments myself except for the horns. This new album was four or five of us going to the studio every day, a real collective effort."
