AVQueuePlayer

Hi guys. Am trying to stream mp3 songs using AVQueuePlayer. I can play the songs well but am stuck on how I can fetch the title of the current playing song and update the UI. Below is the code snippet on how I am playing the songs.

   NSArray *trackDataArray = [trackJSON objectForKey:TRACKS_KEY];

            musicArray = [NSMutableArray array];

            dispatch_async(dispatch_get_main_queue(), ^{

                for ( NSDictionary *trackDic in trackDataArray )
                {

                    AVPlayerItem *thePlayerItem = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:[trackDic objectForKey:TRACK_URL_KEY]]];

                    [musicArray addObject:thePlayerItem];
                }

                audioPlayer = [AVQueuePlayer queuePlayerWithItems:musicArray];

                [audioPlayer play];

                [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd:)
                                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                                           object:[musicArray lastObject]];

Also I would like to reset the player so that when the end of my music list is reached. 

 -(void)playerItemDidReachEnd:(NSNotification *)notification
{

    //Reset the player to the first item in the array    
}

I will really appreciate any help. Below is an example of the json response am using

{
tracks:
  [
     {
         title: "Matter of time",
         artist: "Anna Lena",
         trackUrl: "http://..../song.mp3"
     },
  ]
}
