I don’t use streaming services, so I could be wrong, but I see those are on Tidal, and I believe Roon only updates things like this once you have added a streaming song to your Library.
In the meantime, as I’m looking it appears it updates play count only on songs added to your library, can someone confirm?
My use case is add potential artists, albums to a “to listen playlist” and if I like them, will add them to library. However, in this playlist, I’d like to listen only to songs that have “0” for the play count (vs manually tracking and deleting the listened to songs continually).
