Twenty songs were selected to compete in the national final, which consisted of four shows: two heats, one semi-final and a final. In the heats and the semi-final, four entries were selected to advance from each show: two entries selected based on a public televote and two entries selected by a four-member jury panel. Four songs ultimately qualified to compete in the final on 28 February 2016 where a public vote exclusively selected "Heartbeat" performed by Justs as the winner.
