How do I edit MP3 details on Linux Mint?

Yes. You generally use a tag editor rather than the file manager’s Properties window. EarTag is a straightforward option for editing common fields, while Kid3 offers more controls if you need them.

For a clean-up job across a music collection, MusicBrainz Picard can look up and organize tags. You can then use a separate tag editor for any final corrections. If you only have a few files, that extra step may be more than you need.

EasyTag is another option with a graphical interface. Check your software manager or available Flatpak apps for a tag editor, then open the MP3 and save the fields you want to change.

If you prefer working in a terminal, ffmpeg can write metadata too. For occasional edits, though, a dedicated tag-editing app is usually easier because you can see the fields and edit several at once.
