Is there an App that can read the tags on my mp3 files and apply the correct album art? preferably size 600x600. I have been using https://bendodson.com/projects/itunes-artwork-finder/index.html to find the correct artwork and with over 4,000 albums it is becoming a pain to manually search each album and manually apply to each song. Thanks.
One way to do this is using the "Picard" app from MusicBrainz. This reads the 'audio signature' of your MP3s and finds teh actual tracks in its database, and can then do lots of useful things with the metadata - so correcting track / artist / album names if needed, and adding the correct artwork for the tracks / albums. It can also add lots of extra information that is cool but not something you'd necessarily go looking for yourself (like who wrote the song, what the release date was etc.).
