See → Build a Smart Playlist based off Track Rating with secondary filter to remove Duplicates? for context.
Currently there is no way to apply a secondary filter to remove duplicate tracks from the same artist.
Scenario:
- Rate one single track you know is in multiple albums on your plex server, just rate one. In this example, Piano Man from Billy Joel which is in 4 different albums.
- Now create a advanced filter to find all tracks with that rating.

Result:
What happens is that four tracks are returned from the advanced search/filter as that song appears in 4 albums.
Desired Result:
A way to add a secondary filter to just return one of these tracks and remove the duplicates.
BTW… I’m unable to vote on my suggestion due to the 5 vote rule !
