Hello,
Not sure if this was raised before but would it be possible on Music libraries, to have an option (like a completionist option or sth), that shows all albums of an artist that is already in your library but have those records missing as greyed out?
From there for example you can manually choose to remove some that you are not interested in ever getting or are incorrect for whatever reason.
I think this would massively help people to locate potential gaps in their collections especially if it’s a filterable options like show a list of all missing library albums from existing artists.
