I want the Spotify app to notify my iOS app, when my app is in background. Is it possible?

[Mitesh]

I implemented SPTAppRemotePlayerStateDelegate methods into my app and i am getting notified when my app is active. Spotify is notifying me via 

playerStateDidChange method.

func playerStateDidChange(_ playerState: SPTAppRemotePlayerState) { }

But not getting notified when my app is into background and i am doing something into Spotify i.e song change etc..

Can someone please let me know how can i achieve this.

Thank you
