The song "Crown of Love" by Arcade Fire explores the idea of fading love and the challenge of keeping love alive. The lyrics follow a story of a relationship that has gone downhill due to one partner's inability to remain committed. The singer realizes that the "crown of love" has fallen from them and that the spark of their relationship is gone. Despite this, they still hope for forgiveness from the other person and that they can regain the love they once had. By the end of the song, they are left in an uncertain place, hoping that the other person will continue to love them despite the changes their relationship has gone through.
