"The Sky Is Fallin'" was written by Queens Of The Stone Age frontman Josh Homme and bass player Nick Oliveri. Homme sings lead on the track, which seems to deal with the waves of negative thoughts that can make it feel like the world is ending. He didn't agonize over the words.
"We put the music together and Josh did those lyrics on the fly," Oliveri told Songfacts
. "Changed them a couple times, but pretty much did that on the fly. 'Close your eyes and see the sky is fallin'."
