I Finally Found The Song

I've heard it in a Pixar movie. A Pixar video. On Unforgettable. On The Mentalist. On Supernatural. On The Good Wife. On Franklin and Bash. On Community. I never knew what it was. But I stumbled across it. I found it! It's Intro by the XX. You'll probably recognize it as that song that plays when they catch the killer or comfort the victim.
