title: Persist a MPMediaItemCollection Object Using NSUserDefaults
body: <p>How do you persist a MPMediaItemCollection object using NSUserDefaults? The MPMediaItemCollection object is a single song selected from the iPod.</p>
  
  <p>I have been struggling with this for hours! Anyone have any ideas or alternatives to NSUserDefaults or a conversion from MPMediaItemCollection, or anything?!</p>
  
  <p>Thanks...</p>
