Yes, true, U2.
But should this thread be renamed 'bands you don't like'??
So how do I justify my nomination of Coldplay and U2? Well, they do have some good tunes, undeniably. And I did like U2 pre 'Sunday Bloody Sunday' era... but they just got too, I guess, full of their own self importance. It's not that either aren't talented musicians in their own rights, but just not worthy, imho, of the adulation (and crowds) that both get. There are 'worse' bands... but you kind of know they're crap; there's no illusion about it. U2 and Cp think they're better than they are, imo.
Radiohead may be depressing (an accusation often thrown at them) but they are innovative and challenging in a way that other bands can only dream of being. They'll risk 'changing the formula' because it's what they (or only Thom York perhaps?) want to do.
REM have had good, bad and indifferent albums... but they remain for me, whilst being nowhere near my favourite band, capable of producing sublime pop tunes at an almost whim. Definitely NOT an over rated band, even though hugely popular.
Edit: interesting corollary; there's a David Bowie evening on the tele at the moment, and it's really good listening. Again, I wouldn't rate him as a favourite of mine but the guy's talent is undeniable.
