passing a long a tip that was provided to me:
if you would like to find artists which are missing mood/style/similar tags, there isn’t a good built in way, but you can do the following;
the instructions are nearly the same as @ [TIP] --- how to create an autoplaylist with random sort
- go to https://app.plex.tv/desktop
- navigate to your music library
- go to the library section, if not already there (not the recommended or playlists)
- ensure that artists display is selected
- click the
all
drop down and selectcustom filter
- at the very end of the URL in the web browser, add one of the below (not all of them) according to what your looking for:
–&filters=count(artist.similar)=0
>> artists without similar artists
–&filters=count(artist.style)=0
>> artists without style tags
–&filters=count(artist.mood)=0
>> artists without mood tags
–&filters=count(artist.genre)=0
>> artists without genre tags
example url:
https://app.plex.tv/desktop#!/media/server-id/com.plexapp.plugins.library?typeKey=%2Flibrary%2Fsections%2F11%2Fall%3Ftype%3D8&key=%2Flibrary%2Fsections%2F11%2Fall%3Ftype%3D8&pageType=list&context=content.library&source=11&save=1&customFilter=1&filters=count(artist.similar)=0
those above filters should display what artists are missing the selected tag.
you can save the URL to your browser favorites to easily reload
once the artists are listed, you can select them all (checkbox the first and shift checkbox the last)
and ‘refresh metadata’ (from the 3 dot menu)
to hopefully get that field (re)filled out.
