I wanted to put in a hearty recommendation for the Python application “Beets” -
You have to install python etc., but it’s easy - just follow the instructions!
This is amazing to really organize the music library on Volumio. It automatically detects your music and pulls in the correct information from MusicBrainz, Discogs, etc. - and properly tags and organizes your files and directories. It’s very simple to use, but also very configurable and powerful so you can get your music organized just how you like it.
It’s really amazing and I couldn’t deal with my large library of music without it.
It’s so good, it should become part of the Volumio installation!!!
