"I'm a dreamer, but it's hard to sleep when your head's not in this," begins Birdy on her latest single, "Wild Horses," off her newly released Beautiful Lies. "I will move on, and you should know I mean it," she continues. "Wild horses run in me." It's an empowering kiss-off anthem for anyone tired of shouldering the emotional ruin of a past-its-time love affair. Here, in an exclusive performance for ELLE.com, the UK songbird—who also recently reimagined her cover of Bon Iver's "Skinny Love"—puts the heart back into heartbreak.
