Guitarist Anand Wilder explained to MTV News about this funky and pulsing number: "I wanted to do this loopy thing that would go over and over again, kind of like that final scene in Trainspotting, and then it would just drop into this R&B, Justin Timberlake-y kind of thing, which I made the melody by just creating MIDI notes on GarageBand with just a flute. That had some acoustic guitar on it... but then when we brought it Upstate, we added more synthetic elements, and we kind of decided the beat was going to be a dancehall thing, because we were listening to a lot [of it] and just kind of straight ripped off those songs."
Wilder (From Drowned In Sound): "I was trying to sing a song that Justin Timberlake would sing and the really long intro I wanted to be something like a late '90s Blur song, but then we reconceptualized it as an early '90s club anthem. We wanted it to sound like a future band, all these different things coming in, like there's even a country and western guitar in there, but then it all comes in with a kind of Beatles-esque chorus, very simple, clichéd."
George Harrison's 1971 song "Bangla Desh" was the first major charity single. It was part of a concert held to bring relief to the people of Bangladesh, who were fighting for independence and suffering from a famine.
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."
