U2 singer Bono Vox has said that he is ashamed of many of the band's songs, and that he still doesn't like the group's name.
The band, formed by schoolmates from Dublin, have sold more than 150 million albums over a 40-year career.
But in podcast Avords Four, the 61-year-old said that apart from 2004's Vertigo, he finds it hard to listen to their music.
He added that his voice in earlier recordings sounds "very strained".

"I was in the car when they played one of our songs on the radio, and I got - as we say in Dublin - crimson (turned blue)," he told The Hollywood Reporter's Scott Feinberg during an hour-long interview.
"I'm just uncomfortable. I think some of our songs are embarrassing.
"And the lyrics too. On the album Height (Boy) and other albums featured very unique and original material. But I don't think I filled it with details."
In defense of the band - 10 albums was number one in the UK and have had seven chart-topping singles since their debut in the early 1980s.
Radio 2 listeners recently released their fifth album Joshua Tree - with hits like With or without you i Where The Streets Have No Name - declared the best album of that decade.
Although Bono agrees that his band "sounds amazing", he said he doesn't like his own voice at all, except in Vertigo, from the studio album How to Dismantle an Atomic Bomb.
"Most of the other songs gave me chills," he said.
And despite a career spanning four decades, Bono believes that his voice used to sound weak and that he "only recently became a singer."
"I think my voice was very strained before and somehow it's not macho, it's mine Irish macho he wasn't happy about that," he continued.
"The big revelation for me was listening to the Ramones and Joey Ramone's beautiful voice and realizing that I don't have to be that rock and roll singer.
"But I only recently became a singer".

"We chose the name we hated the least"
Bono made a guest appearance on the podcast alongside bandmate The Edge (The Edge), who also revealed that the group members were never particularly fond of the famous name.
U2 was, as he explained, originally supposed to be called The Hype, but they rejected the idea because the name didn't sound original to them.
Their friend, graphic designer Steve Averill then made some suggestions.
"U2 "it didn't really jump out as the name we were really looking for, it was the one we hated the least," said the guitarist.
He said it sounded "fresh" at least at the time, and that "it wasn't obvious from the name what this band was going to sound like or what it was about".
"We chose that and we didn't really like it at first."
"I still don't like it, I really don't," Bono continued.
"But I had some kind of dyslexia, I didn't even realize that The Beatles (The Beatles) bad pun". (word beetle in English it means bug).
The band, he said, thought their name would conjure up "futuristic" images of "spy plane" and "submarine".
Bono and Edge made guest appearances on the podcast to promote it Song 2, an animated film starring Matthew McConaughey and Reese Witherspoon.
The singer voices a character in the film, while he and Edge co-wrote the song You Saved My Life from the movie soundtrack.
