"The punk rock thing to do is annoy people and get in their faces," he said. "If people have a problem with the way we released the album, I'm sure they've read about it online."

Bono's talk of punk rock didn't end there. He also explained the band's Songs of Innocence tribute to Joey Ramone, "The Miracle (of Joey Ramone)." Apparently, when Bono was just starting out, he had the realization that his singing voice wasn't very masculine - an asset that ended up helping him front U2 - and Joey Ramone's music made him feel like it was okay.

""I realized that I sang as a girl and I was a bit depressed about it as a young Irish male," he recalled. "And then I realized Joey Ramone sings like a girl. He was inspired by all those great sirens as well as everything else. He has a beautiful melodic voice. And if I could be so lucky, I might try to have one of those."
