He tells a BBC Radio 4 documentary: "YouTube, they're the devil. We don't get paid at all. If someone doesn't do something about YouTube, we're screwed. It's over. Someone turn off the lights. It's hard to make people pay for what they've been getting for free. That's consumer behaviour 101."

Mensch dismisses the video streaming site's current business model, which is heavily reliant on adverts as 'unsustainable.' His comments came during the BBC Radio 4 documentary, The Business of Music, which is available on the BBC iPlayers with part two to follow on April 25.
