• The origins of this moody, electronic ballad were a rejected demo that had one little part which the band liked. "Some songs we'll come up with demos, and they won't ever turn into anything... we'll hear them, and we'll know they're not ever going to be a great song on their own," Mike Shinoda told MTV News. "But there may be a section of it, a little glimmer of cool something in it, and the song 'Until It Breaks' is built from just those. There were like four demos that we had made that weren't going anywhere individually, but when you put them all together, they make something really interesting. It's supposed to feel really jarring and weird, and for me it was a really fun song to make."
• Guitarist Brad Delson provides a rare vocal on this song.
