Okay but Spotify should really add more Ed Sheeran songs... Like Sara & You need to cut your hair... Like all of his old old stuff *-*
Hello @saraHM96 and welcome to the community.
Spotify adds all music that is made available to them - unfortunately they do not own the rights to every track in the world. As soon as they are allowed, they will certainly add the music you ask for. Hang in there!
Btw: The ideas board is not the correct place to talk about these kind of things; I'd advice you to post those type of questions in the "Help - Other" section of the community.
