title: Prevent MPMusicPlayerController from playing next song in que
body: <p>I am creating an app that has a playlist and uses the MediaPlayer library. When a song ends I don't want the next song to start. I tried to use the MPMusicPlayerControllerNowPlayingItemDidChangeNotification to pause the music player when the song changes, but the song starts to play before I get the chance to stop it. I also tried to use KVO to track the changes to musicPlayer.currentPlaybackTime, but I only receive messages when i manually change the playback time. I can't find any information about this problem anywhere.</p>
