The Edge has revealed he had his doubts about releasing U2's latest album Songs Of Innocence as an automatic download for Apple users.
The musician told The Observer's The New Review: " I absolutely had my doubts about it before we did it, and after, but it was the right thing to do.
"It was an opportunity that will only ever come around once for anybody. I don't think anybody would want to do it again."
Bono said however that he stands by the decision even though it annoyed a lot of people. He said: "We were already annoying people, it was already divisive, it was already, 'I can't stand them, I want to kill them'. It's the job of art to be divisive."
Bassist Adam Clayton added: "The plan wasn't to be controversial. In today's world there is so much chatter, so in order to get through the chatter I'm afraid we are destined to make a very loud noise ourselves."
