here's a copy/paste from U2Songs.. all songs where we've had some descriptions.. (save Best Thing, Little Things, etc)
Other titles mentioned recently expected to be in contention for the album:
“The Showman” (Mentioned in MOJO Magazine, February 2017 where Bono calls it his favorite, and says it is about singers, “The showman gives you front row to his heart, The shaman prays that his heartache will chart”). Bono mentioned the song again during the Zane Lowe interview.
“Tightrope” (Mentioned in Entertainment Weekly, Oct. 2015, “It’s very epic. It’s very up. And, you know, that’s probably what the experience has taught us: to be fully in the moment and that fun is respected, and joy is not to be let go of.”)
“Landlady” (Mentioned in Q Magazine, Feb. 2016)
“Much More Better” (Mentioned in Q Magazine, Feb. 2016, “deeply personal acoustic demo about Bono’s recovery from his bike accident.”)
“Summer of Love”(Mentioned in MOJO Magazine, February 2017 where Bono says the song is “achingly beautiful and empty. It could be a big song and it’s tiny. These are real tunes.”)
“Get Out of Your Own Way” (Mentioned in Q Magazine, Feb. 2016 and by the Globe and Mail in May 2015 where reporter Marsha Lederman states, “They were talking about getting of your own way, not to fight with yourself, in striving to perform at the top of your game.”)
“Civilisation” (Mentioned in Q Magazine, Feb. 2016, “sounded like a surefire album opener. Bono described Larry Mullen’s colossal drum roll in the middle of the song as ‘my favorite bit on a U2 album in years.’”)
“The Morning After Innocence” (Discussed on BBC Radio on October 16, 2014, “You never could write so well or do anything you were told on 10 Cedarwood Road, I’m your older self, the song of experience, I’ve come to ask for some help from your song of innocence.”)
“Instrument Flying” (Mentioned in Q Magazine, Feb. 2016, “had a sleek, motorik quality.”)
“Love is All We Have Left” (Small bit of audio leaked on Instagram in September 2016)
