What Are You Listening To Right Now?

Heard that song a while ago but don't recall where. I know I didn't watch the anime it was used on. https://www.youtube.com/watch?v=2AfIQX8YUVw

Oh wait, it was used for Erased's second ending. That's where I heard it from. I saw a post saying it was used for Rampo Kitan: Game of Laplace but I haven't watched that so it threw me off lol. No wait I'm an idiot, it wasn't used on Erased. Ugh, I should get some sleep.
