Mark Ronson banned all cover songs on his new album 'The Business'.
The music producer - whose 2007 album 'Version' featured successful covers of songs by Kaiser Chiefs and Coldplay, among others - said this time around he had got artists to collaborate with him on original songs, which had been a fun and "interesting" process.
The 34-year-old told NME.com: "There's no covers, and no horns. It's written with some of the people that actually wrote the songs I covered on the last album and that I didn't actually even know at the time.
"It's quite interesting to write songs from scratch with those people, like Dave McCabe of The Zutons who wrote 'Valerie', and Nick Hodgson, of Kaiser Chiefs."
Mark also revealed he had collaborated with Santigold, Scissor Sisters, Cathy Dennis, rapper Pill and Mike Snow for his forthcoming album, 'The Business'.
Speaking on when it was likely to be released, he said: "Probably May, June depends how quick I can get it done".
