I wrote a little script in
python, I am reporting it here since someone else may interested in tag grabbing.
The deep details of musicbee let you integrate those tags and create playlists/Hightlights/Custom TAGS based on some
features like Danceability, Instrumentalness, Valence, Energy and mode.
The result, which may need some more tuning and tinkering, may looks like this:
It's of course possible to add these metrics on your current auto-playlists, adding keywords as appropriate as the new features can easily be custom-mapped as "Ratings"; I always wanted a "songs in minor" playlist.The Tags are added under TXXX user texts, with codes SPTY_* so that should't interfere with other tagging techniques
