title: MPMusicPlayerController doesn't skip to the next item automatically after using a predicate
body: <p>i'm developing a music player app.I have a tableView that contains the songs names of the ipod library.My problem is that when i select a cell it plays a specific song but when that song is completed it doesn't skip to the next item automatically.
  This is my code when i select a cell:</p>
  
  <pre><code>MPMediaQuery *mq  = [MPMediaQuery songsQuery];
  MPMediaPropertyPredicate *songNamePredicate = [MPMediaPropertyPredicate               
  predicateWithValue:[songsTitle objectAtIndex:indexPath.row]     
  forProperty:MPMediaItemPropertyTitle];
  [mq addFilterPredicate:songNamePredicate];
  [mp setQueueWithQuery:mq];
  [mp play]; 
  </code></pre>
  
  <p>i really need your help.Thanks.</p>
