Nowadays I’m practically using plexamp far more often than I watch my own video content on Plex. I started using Plex for music about 6 months ago and plexamp has been such a powerhouse of a music app in ways I never expected. I really appreciate the specific DJs they give you with sonic analysis. I’ve realized it’s also made me enjoy buying CDs again, which are especially cheap these days!
You can make user profiles for your family members so they fall under your plex pass. Worked for my house so far.
