It must have a option to transfer music from another provider to Spotify, like iTunes or dezeer, anghami .... If you a new user and you used to listen to the music on another provider and you have 2000 song and you can't transfer this 2000 songs to spotfy it's a problem , you can't add this songs by yourself it's very difficult to add ! .
