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!
I use it constantly on all my devices. Also, I have it setup headless on an Hifiberry streamer, connected to a Yamaha amp. It’s great!
