"I thought 'pop' was a term of abuse, it seemed sort of insulting and lightweight. I didn't realise how cool it was. Because some of the best music does have a lightweight quality, it has a kind of oxygen in it, which is not to say it's emotionally shallow. We've had to get the brightly coloured wrapping paper right, because what's underneath is not so sweet."
- Bono describing the difference between the "surface" of the songs to "what lies beneath".

During the recording sessions of Achtung Baby, the band were working on a primitive version of Mysterious Ways called 'Sick Puppy'. During these versions, The Edge improvised a chord progression that the rest of the band worked with. From that chord progression the song 'One' was born, ultimately changing the outlook of the sessions and more importantly, keeping the band together.
