In this song vocalist Jón "Jónsi" Thor Birgisson's sings for the first time in Sigur Rós' recording career in English.
Birgisson told The Sun July 4, 2008 why this was his first song sung in English: "It's something to do with my accent that I've never done it before - it sounds harsh. But I was pleased because it turned out really well. I was very worried about it but you have to let go. I do speak 50/50 Icelandic and English, because my boyfriend is English, as are my manager and people at my record label."
Fall Out Boy's "The Kids Aren't Alright" song title is not a reference to The Offspring's 1998 single of the same name. It actually alludes to The Who's 1979 rockumentary film called The Kids Are Alright.
