Here, OK Go frontman Damian Kulash sings of a couple's intense desire for each other. Kulash normally dreads writing lyrics as he prefers the way music can incorporate differing emotions all pulling in contrary direction. However he found the words for this song came easily. Kulash explained to Purevolume
"I love music precisely because it can say things that language can't; it can communicate emotions that are more complicated and more raw. So if a great song pushes your heart one way while pulling the opposite, what can you say over it that won't screw it all up? Most words just literalize one of the component emotions and collapse the whole thing into a single dimension. It's a vicious riddle to solve, trying to balance the warring emotions without highlighting just one, or devolving into meaningless abstractions to intentionally keep it vague.
This is one of the rare songs where the feeling in the music screamed so loudly that writing lyrics wasn't such a fight. As soon as we had the basic foundation of the song laid, it was obvious what this one was about: obsession."
