title: How is it possible to know what's spotify is playing from an external Android app?
body: <p>I just found out this settings option in Spotify for Android settings screen: </p>
  
  <blockquote>
    <p>"Device broadcast status - allow other apps on your device to see what
    you are listening to"</p>
  </blockquote>
  
  <p>I guess that means any other app can access what's being played via Spotify. How can this be implemented? Is there any documentation around?</p>
  
  <p>Thanks</p>
