The original
Kid3
Edit audio-file tags individually or in batches.
Replacements
Listings that take over the same core job as Kid3.
Mp3tag
A tag editor that fixes the metadata of a whole music folder at once, with online database lookups.
Mp3tag adds online lookups from Discogs and MusicBrainz and regex replacements, but it is closed source, free only on Windows, paid on macOS and has no Linux build.
MusicBrainz Picard
The official MusicBrainz tagger, which identifies music by its audio fingerprint and fills in the tags.
MusicBrainz Picard is also free and open source on all three desktops, adding AcoustID fingerprinting and album-oriented matching, though it needs an internet connection.
TagScanner
Rename music files and edit their tags in batches.
TagScanner is a free, closed-source Windows-only tool for batch tag editing and renaming files from metadata, with online tag retrieval that Kid3 users may not expect.
beets
Organize a music library from the command line.
beets is a free, open-source MIT tool that organises a library and improves metadata during imports, but it works from the command line instead of a graphical editor.
Metatogger
Clean up music tags and filenames with a Windows library utility.
Metatogger is a free, closed-source Windows-only utility for batch metadata editing that adds tools for identifying recordings and proposes changes for review.
