Hi USe the below code and try it

        define('BASE_DIR','songs');

        // log downloads?  true/false
        define('LOG_DOWNLOADS',false);

        // log file name
        define('LOG_FILE','downloads.log');

        // Allowed extensions list in format 'extension' => 'mime type'
        // If myme type is set to empty string then script will try to detect mime type
        // itself, which would only work if you have Mimetype or Fileinfo extensions
        // installed on server.
        $allowed_ext = array (

        /* // archives
         'zip' => 'application/zip',

         // executables
         'exe' => 'application/octet-stream',*/

        // flash
  'swf' => 'application/x-shockwave-flash',
        // audio
  'mp3' => 'songs/mpeg',
  'wav' => 'songs/x-wav',
  'aif' => 'songs/aif',
  'aiff' => 'songs/aiff'
        );
