"Every day I turn around and think, 'What the fuck was I doing? How did I get here?'. I did not own any of their records at all. Not even Achtung Baby, not Zooropa. I came into it totally fresh."
- Howie B on working with U2 for Pop
U2 intended to release No Line on the Horizon in November 2008; after composing 50 to 60 songs, they postponed the release because they wanted to continue writing.
