Calvin Harris has compared making pop songs to making a ham sandwich in an interview thing for The Guardian.
Talking about the 'secrets of his success', the 'This Is the Industry' hitmaker said: "It's [making pop songs] incredibly easy to do, but hard to do perfectly."
"I'd struggle to make a perfect ham sandwich because I never make them, whereas pop music comes naturally to me – it's what I do every day."
So there you have it.
