MPMoviePlayerViewController to stream Mp3's

I am trying to stream an mp3 using MPMoviePlayerViewController. I realize this was (obviously) meant to be used for movies, but I read that I could use it to stream mp3's as well.

Once the MPMoviePlayerViewController loads, the "Loading..." screen comes up and a couple of seconds later it just closes down. The problem doesn't seem to be with my url since I can plug it into a browser and the mp3 downloads just fine.

Here is my code:

NSLog(@"OpenFlowVC: url: %@",url);
    MPMoviePlayerViewController *playerVC = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
    playerVC.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
    [self presentMoviePlayerViewControllerAnimated:playerVC];
    [playerVC autorelease];

The strange thing is, this works for some mp3's but not others. Any input would be appreciated. Thanks

Have you checked the real format and encoding of each MP3, try to use some tool that would give you all this information (Try this one free) They may be all files with mpp3 as extension but not all the same way encoded. Compare a working with a non working mp3.
