40. "Love Is Blindness"
This pulsating, celestial-effects ballad, the concluding track on Achtung Baby, wasn't originally intended for U2; Bono wrote the song (on piano, which he rarely did) with R&B-soul diva Nina Simone in mind before U2 kept it for themselves. The Edge has said the song has "probably one of Bono's finest lyrics"; the reference to "a little death," Bono has said, "can be taken to mean a faint during orgasm but also works as an image of terrorism. ... I was mixing up the personal and the political." The personal factored into the music as well: Recording his solo, the Edge, who was separating from his wife, "played until the strings came off," Bono said.
