Short description of MusicBrainz Tagger 0.10.5: The MusicBrainz Tagger application allows you to automatically look up the tracks in your music collection and then write clean metadata tags (ID3 tags or Vorbis comment fields) to your files. As you tag the files in your collection that MusicBrainz didn't recognize, you submit the acoustic fingerprints (TRM ids) of your files back to the server.
