I successfully prevented Plex Web and Plexamp from playing any track twice by adding “Track Plays = 0” to all Smart Playlists and Smart Collections in my music library. The goal was to guarantee playback of all 14k hand-picked tracks before repeating. It works like a charm!
In the distant future, likely one year from now, I will need to revise “Track Plays = 1” to allow another round of one and done playback. My suggestion therefore is as follows.
Add a single-click option to Smart Playlist, Smart Collection filtering to automatically bump the Track Plays filter count by one when no track matches the current setting.
