Mark Ronson feels like he is 'past his sell-by date'

The 'Uptown Funk' hitmaker, who will turn 40 next week, has admitted he sometimes feels too old to be a popular musician but takes comfort in the fact other older musicians such as Pharrell Williams still manage to create chart-topping hits.

He said: "I'm so far past my sell-by date of what pop music is supposed to be.

"But, if you look at it, Pharrell and Daft Punk are around that age. So maybe there's something to be said for experience."
