"The last two albums, Songs of Innocence and Songs of Experience, broke a rule of ours, which was to keep looking forward and keep going, to not stop or look back and turn into a pillar of salt. But opening up to questioning why you do things, and about how you grew up and why you ended up where you ended up and all of those kinds of questions, once I opened that door, I couldn't close it."
- Bono, 2022

U2 changed many of the tracks' names of No Line On The Horizon during recording, retitling "French Disco" to "Magnificent" and "Crazy Tonight" to "I'll Go Crazy If I Don't Go Crazy Tonight". "Chromium Chords" became "Tripoli", and finally "Fez – Being Born".
