Rob is always seen taking his guitar on set with him and has spoken openly about his love for writing and performing music. And when Rob performed for Songs from a Room last year, an event which showcases up and coming artists, we were blown away by his performance.
Rob's inimitable style makes it hard to tell exactly the lyrics he's singing but from what we can grasp, he appears to be talking about being away from his heart's desire. Could the song have been inspired by spending long amounts of time away from his girlfriend, Kristen Stewart?
