Watch for MPMusicPlayerControllerNowPlayingItemDidChangeNotification, and in your selector method, check the playbackState for MPMusicPlaybackStateStopped, do other checking (maybe nowPlayingItem?), and present your view.

NSNotificationCenter * notifications = [NSNotificationCenter defaultCenter];
    [notifications addObserver:self selector:@selector (trackDidChangeWithNotification:)
                          name:MPMusicPlayerControllerNowPlayingItemDidChangeNotification
                        object:self.iPodController];

.....

-(void)handleNextTrackNotification {
    if ([self.iPodController playbackState] == MPMusicPlaybackStateStopped) {
        // do whatever logic checks
        // present view
    }
}
