Singer/guitarist Jared Leto about song: "That's the left side of my brain, me in the darkest corner of my soul. It's a pretty sexual song as well, which is an area I don't normally delve into. When you want to tell a story, you want to explore all the avenues and angles. I felt I needed to reveal more of myself. It wasn't hard, but it might be surprising for some people. It's an electronic song, and we built all the sounds up from scratch; we didn't use anything pre-programmed. I think it's pretty unique." .
