title: iPhone SDK - check iPod playlist to see whether there is a next track to skip to
body: <p>Is there a way to inspect the current playlist from MPMusicPlayerController to see whether there is another track to play in the queue?</p>
  
  <p>It's possible to detect this after as skipToNextItem will stop playback and change playbackState, but I want to find out before, so I can disable the skip track function if there are no more tracks to skip on to.</p>
