"One of the reason's for U2's longevity is that they are not in music for entirely selfish reasons. I don't want to make them appear as evangelists, which, of course, they were seen as by some sections of the music media in the early 80s, but I do believe that they really think what they do serves some greater purpose than simply filling their bank accounts."
- Brian Eno, 2009
Starting from Summer 2007 to Summer 2008, U2 had written and recorded 50-60 songs for a new record with Brian Eno and Daniel Lanois. 11 of these were released on 2009's No Line On The Horizon.
