"You can't repeat yourself. You can't rely on things that have been done before by anybody else, you've got to find new territory. So every time we go into the studio and every time we sit down to start talking about a live production, we ask ourselves the same question: 'What's never been done?'"
- The Edge on the 360 tour

In late 2004, "Mercy", an unreleased track taken from the How to Dismantle an Atomic Bomb sessions, surfaced on the Internet through a fan who had been given a copy of the album containing the extra track. The track is of less than standard audio quality, but managed to become a favorite on fan websites.
