'So Cruel' is a cover of the U2 song of the same name recorded by Depeche Mode for the tribute album AHK-toong BAY-bi Covered. The tribute album was released in the United Kingdom on October 25, 2011, and was subsequently released via iTunes as an album-only track.
Martin Gore: "We first heard Achtung Baby working on Songs Of Faith And Devotion with Flood. It was the closest our bands ever got: U2 had become more electronic while Depeche Mode were working on a new rock vision. But there was never a rivalry. Bono used reverse psychology in his email, saying he totally understood why we'd say no. We just thought, Why not? 'So Cruel' is Bono at his best, words-wise. And we couldn't tackle 'One' - that would be almost sacrilegious."
