This track features vocals by Angels & Airwaves' Tom DeLonge. "He's, like, my childhood hero who's become a friend of mine," Say Anything frontman Max Bemis noted to Billboard magazine. "He took one small suggestion and built this crazy, awesome, layered thing. I don't tend to think about myself as some kind of huge success story and don't pat myself on the back too often, but when I heard that, I just thought, 'What the hell's happening with my life?!' I was doing a little schoolgirl thing in my house."
There was a rumor in the Soviet Union that The Beatles had secretly visited the U.S.S.R. and given a private concert for the children of top Communist party members. They believed the song "Back In The U.S.S.R." was written because of the concert. Actually, some fans still believe so.
Kacey Musgraves originally offered "Follow Your Arrow" to her friend Katy Perry. However, Perry thought Musgraves should record the song herself as it seemed, "like something that you would totally say."
