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.
Got a bunch of MP3 files with missing tags? Get 1st MP3 Tag Editor and get them filled in automatically, without lifting a finger. The program will automatically connect to a database and import song name, album title and other tags based on track length and other properties. (Internet connection required) Other options are tag based file (re)naming, extensive tag editing option, batch file processing, playlist creation, Amazon and CDDB support.
