title: com.android.music.musicservicecommand doesn't stop spotify
body: <p>Hey I'm using this code Snipped to stop the music play in Android:</p>
  
  <pre><code>Intent i = new Intent("com.android.music.musicservicecommand");
  i.putExtra("command", "pause");
  Context.sendBroadcast(i);
  </code></pre>
  
  <p>So everything is alright, while e.g google play music is running, but this snipped doesn't stop spotify playback.
  Is it just for me or is it a general Problem and is there any solution for it?</p>
