Sigh. "Where Do Broken Hearts Go" is probably the #1 One Direction song that should have been a single but never was. It was classified as a promo single, but it never got a music video or anything. The band performed it on tour and at some promo events, but it should have been on the radio, because this is a certified jam. Harry Styles cowrote this one with other popular songwriters RuthAnn and Teddy Geiger.
