OS 5 now supports setting the track title as well as an album art image in both the lock screen and the remote playback controls (the controls you get when you double-click the home button and swipe right). Take a look at the MPNowPlayingInfoCenter class. Of course, to maximize compatibility, you'd want to test whether MPNowPlayingInfoCenter is available, by doing something like

if ([MPNowPlayingInfoCenter class])  {
   /* we're on iOS 5, so set up the now playing center */
   UIImage *albumArtImage = [UIImage imageNamed:@"HitchHikersGuide"];
   albumArt = [[MPMediaItemArtwork alloc] initWithImage:albumArtImage];

    NSDictionary *currentlyPlayingTrackInfo = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"Life, the Universe and Everything", [NSNumber numberWithInt:42], albumArt, nil] forKeys:[NSArray arrayWithObjects:MPMediaItemPropertyTitle, MPMediaItemPropertyPlaybackDuration, MPMediaItemPropertyArtwork, nil]];
    [MPNowPlayingInfoCenter defaultCenter].nowPlayingInfo = currentlyPlayingTrackInfo;
}
