In reference to the song, lead singer Elliot said in the album's commentary that "All I Want Is Everything" was "demoed as almost a country song, [the song] went through a lot of changes in the studio." Elliot also says that the song has "almost a U2 feel to it", and the "very solemn" lyrics sum up "a lot of what the band was going through at the time: births, deaths, divorces."
