Bono doesn't like the name of his band... or the sound of his own singing! The Edge explained that the band's first name was The Hype but they weren't happy with it because it wasn't original. They went to their former classmate and fellow musician Steve Averill for his input. One of them was U2, and the band didn't love it, but it was the one they hated the least out of the all the options he gave.
Bono then added that his feelings haven't changed. "I mean, I really don't. But I was late into some kind of dyslexia, I didn't realize that the Beatles was a bad pun either. We'd thought the implications of the letter and the number, in our head, it was like, the spy plane, it was a U-boat, it was futuristic. But then as it turned out to imply this kind of acquiescence, no, I don't like that name. I still don't really like the name."
He also spilled that it's hard for him to listen to some of their earlier stuff because of his voice. "I just found the voice very strained and kind of not macho and my Irish macho was kind of strained by that. A big discovery for me was listening to the Ramones and hearing the beautiful kind of sound of Joey Ramone and realizing I didn't have to be that rock and roll singer. But I only became a singer recently."
