The song was sort of an accident. Win Butler admitted to Dutch website 3voor12
that he was working on a remix of "The Coffee Cola Song" and he "just ended up writing a completely different song around it without even thinking about it."
Butler continued: "It kind of took a couple of months to realise that 'Everything Now' was a song because we're not really a band that uses sampling or anything like that, so it wasn't something that was on my radar. By the time we played it with the band, it took on a completely different life of its own."
