A requiem is a Catholic mass for the dead. This fits in nicely with the theme of human sadness and may imply that this song serves as the requiem for Julian’s relationship with his father.

Julian Casablancas explained in an interview:

“Human Sadness,” that was something that Alex, the drummer, he brought me the Mozart sample that was the basis. He just played that for me and that had a deep effect on me. I really loved it, and so I would write melodies over it and different parts.
