NME.Com has opened an online poll to find the 'greatest U2 song'.

'Do you fancy 'Sunday Bloody Sunday'' they ask, ' Or is it always a 'Beautiful Day' for you 'When Love Comes To Town'. Can 'One' be 'Even Better Than The Real Thing'. Or would your vote go for 'Where the Streets Have No Name'? '

Whatever your choice, you can vote for it here
