The band are due to headline the festival on June 24 and drummer Larry Mullen revealed they all have different opinions on the set.
Speaking to Zane Lowe on BBC Radio One, Mullen said: 'It's taken a lot of time and energy to figure out what the setlist is going to be.
'There's a Where The Streets Have No Name camp or there is the more subtle approach where we could build slowly. We've gone through a number of combinations and everyone seems to have a different opinion.'
He added: 'We all know who gets his way in the end.'
