Much thanks for your input. Yep. Following a re-scan it’s a mess again. But not totally! A few of them maintained - just a few. Between this sad state and the issue I and others are having with Artists I can not see me moving forward with Plex. I trialed PlexPass so as to have an equalizer in the iOS app, the otherwise excellent Plexamp. I was very hopeful. But I need to navigate my library! I can forgo the EQ and save money with Emby.
