New Filter - Album "Is not rated"

I recently had to wipe my server and lost a lot of my track ratings. I use track ratings and play counts to populate a lot of my smart-filter based playlists for Plexamp.

To speed up the process of rating I created smart playlists that use “Track rating > Is > Is Not Rated”. I then listen to this playlist on shuffle to find tracks I like and rate them. I had the idea to instead rate albums and artists to speed this process up. Unfortunately, There is no such “Is not Rated” for album and artist filters. Could this be added?
Thanks!

2024 clean-up: implemented – this can already be done using an Advanced Filter (w/ option to store that as a smart playlist / collection).

  1. Open Advanced Filter section
  2. Set criteria to Album Rating + Is
  3. Click to the left of the most-left star to set the filter to “none” (or unrated)
