これを行う私のコードの一部を次に示します。

    MPMediaQuery *everything = [MPMediaQuery songsQuery];

[everything setGroupingType: MPMediaGroupingPlaylist];

self.playlists = [NSMutableArray arrayWithArray:[everything collections]];

....

    NSArray *songsList = [[self.playlists objectAtIndex: currentPlayListIndex] items];

int nowIndex = [songsList indexOfObject:nowPlayingViewController.nowPlayingItem];

if(++nowIndex >= [songsList count]) 
    nowIndex = 0;

if(![self playItem: [songsList objectAtIndex:nowIndex]])
