Now I’m a bit of a fan of The Killers, but what’s been bothering me is what does the lyric Are we human, or are we dancer? from their Human song mean. Here’s an answer form Wikipedia.

Initially there was confusion and debate over the line “Are we human, or are we dancer?” in the song’s chorus. Debate raged across the internet over whether the lyrics said “denser” or “dancer”, a misunderstanding which invoked conflicting interpretations of the song’s meaning. Entertainment Weekly’s Pop Watch section called this line the “silliest lyrics of the week”. They were puzzled by the interpretation, stating “most dancers are generally human”. On the band’s official website, the biography section states that Flowers is singing “Are we human, or are we dancer?” and also says that the lyrics were inspired by a disparaging comment made by Hunter S. Thompson, where he stated America was raising “a generation of dancers”. In an interview with Rolling Stone, Flowers said that he was irritated over the confusion about the lyrics and also that fans were unhappy with the song’s dance beat: “It’s supposed to be a dance song, [the beat] goes with the chorus…If you can’t put that together, you’re an idiot. I just don’t get why there’s a confusion about it.” Wikipedia.
