First off, thanks so much for beets! It’s a great and geeky piece of software for a music hoarder like myself.
I have scoured the documentation and my google-fu has failed me. I am trying to albums which has a flexible attribute set. For instance, if I use the flexible attribute mood and add mood:sad, mood:happy, mood:boring to different albums, I would like to list all albums which has any of those set. How can I do this?
Also, is it possible to delete a flexible attribute from the database, as in completely remove “moods” from the database and all assigned albums/tracks?
