      extractor = tar.extract();

   extractor.on('entry', (header, stream, next) => {
      stream.on('end', next);

      if (header.name === fileWanted) {
         const { size } = header;
         res.set({
           "Content-Type": 'audio/flac', // or whichever one applies
           "Content-Length": size,
           "Content-Range": `bytes 0-${size}/${size}`
         });
