Bono thinks U2 are the ''most interesting'' band around.

The 55-year-old frontman insists his group take a lot more risks than anyone else and believes it would be a ''shame'' if they called it a day.

He said: ''I really believe the band is a very special thing and we're taking bigger risks than anybody with a brain would.

''I think we're certainly the most interesting band, love us or loathe us, and I think it would be a shame if we weren't around, really.''

The group were widely slammed when they released their last album, 'Songs of Innocence' as a free automatic download on iTunes, but Bono - who sustained multiple injuries after falling off his bicycle last November - insists he is never surprised when they are blasted by detractors.

He told Q magazine: ''I don't believe in luck. I walk under ladders. I'd have 13 tattooed on my a**e without any problem. But I do think the universe can turn cold and nasty. I'm never surprised when the world gets a bit ugly. I'm never surprised when U2 meets resistance.''

Despite being regarded as the leader of the band, Bono doesn't want to be seen as ''the boss''.

He said: ''I'm into horizontal relationships, not vertical ones.

''It's why I'm in a band. It's why I'm married. It's why I would not like to be called The Boss.''
