PHP returns an MP3 file [closed]

I have a small music application where files are loaded from a URL like " link ".

Locally the application works very well.

But when I put it on the server my application generates an error in the browser console.

  

Uncaught InvalidStateError: Uncaught InvalidStateError: An attempt was   made to use an object that is not, or is no longer, usable.

My PHP code:

 $song_name = $_GET['name'];
 $song_file = "{$_SERVER['DOCUMENT_ROOT']}/assets/musics/{$song_name}.mp3";

 if( file_exists( $song_file ) )
 {
    header("Content-Type: audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3");
    header('Content-Length: ' . filesize($song_file));
    header('Content-Disposition: attachment; filename="'.$song_name.'.mp3"');
    header("Content-Transfer-Encoding: binary");      
    header('X-Pad: avoid browser bug');        
    readfile( $song_file );
  }
