Sinead O'connor has compared U2 to terrorists.

The 'Nothing Compares 2 U' singer has slammed the band's decision to have their latest album 'Songs of Innocence' automatically uploaded into iTunes subscribers' music libraries, describing it as a ''badly-judged move'' and claiming they have ''invaded'' people's lives.

She told The Mail on Sunday's Event magazine : ''What they did with iTunes was a badly-judged move.

''There was something almost terrorist about it.

''I'm really not a U2 fan but it wasn't at all kosher invading people's lives like that. It was bad management.''

The 47-year-old singer accused the band - made up of Bono, The Edge, Adam Clayton and Larry Mullen Jr - of not ''standing by their album'' and choosing instead to ''force it on people who didn't want it in the first place.''

Bono previously apologised for getting ''carried away'' and giving the record away in the way that they did.

He said: ''I'm sorry about that. I had this beautiful idea and we got carried away with ourselves - artists are prone to that kind of thing.

''Drop of megalomania, twitch of generosity, dash of self-promotion and deep fear that these songs that we've poured our life into over the last few years mightn't be heard.

''There's a lot of noise out there. I guess we got a little noisy ourselves to get through it.''
