Marcus Mumford finds it "funny" when people tell him they hate his music.
The Mumford & Sons frontman has confessed he isn't bothered by critics and is often left amused when people slam the band's tracks to his face.
He said: "There was one weird kid who came up to me in a guitar shop in New York. He was very strange and knocking stuff over.
"He stood in the doorway and shouted, 'Mumford and Sons f***ing suck'. Then he turned away and ran. Weird.
"Then another time. I was at a gig when a guy came up to me and said: 'I just want you to know that I f***ing hate your music. It's repulsive'. So I said, 'OK cool, thank you for your opinion'.
"He then added, 'You seem like a nice guy but your music, it just disgusts me.'
"I don't think people are brave enough to say it to our faces most of the time. When people do, I find it very funny."
The band - made up of Marcus, bassist Ted Dwane, 30, keyboardist Ben Lovett, 28 and guitar player Winston Marshall, 27 - recently banned the use of mobile phones at their concerts as they travel the globe previewing their new material in a series small gigs.
While upholding the ban proved somewhat difficult, Marcus claims it has greatly improved the atmosphere of their shows.
He told The Sun newspaper: "That's why we've banned phones from the gig. We didn't want new songs on YouTube before the album is out.
"We've worked so hard on them and by banning phones, we've noticed the energy in the venues was totally different because people were actually looking at each other and communicating.
"Everyone was sharing experience. The small shows have really worked."
