Ed Sheeran is the most streamed male solo artist in Spotify history and has produced some of the most beloved pop songs of the 21st century. Shape of You became the most streamed song in Spotify history at the time of its release and remains one of the most played songs ever recorded. Perfect is his most romantic song — a wedding anthem of such universal appeal that it has been played at millions of ceremonies around the world. Thinking Out Loud won him the Grammy for Song of the Year and introduced him to a mainstream audience that his earlier acoustic work had not reached. The A Team was the song that made his reputation — a devastating portrait of street homelessness delivered with a delicacy that belied his age. Castle on the Hill is his most autobiographical song and his most emotionally direct. Which Ed Sheeran song is truly his greatest?
