Thank you! I use Quad9 and have noticed these links stopped working about a week or 2 ago. The problem was I redid my network at that time and kept thinking it was something on my end. I have a firewall with recursive DNS setup and I was able to add my own entry for it, but I’m guessing the IP changes because it only lasted a few days. Now that I know why I’ll see what else I can do since I do enjoy Quad9 otherwise.

I use a combo of Roku and Firesticks through the house. Since I have a raspberry pi with pihole on it all the ads and telemetry is blocked, or at least majority of it is.

I currently use Navidrome as well, but I really don’t use smart playlists like that. For me, I use Symfonium on Android, which offers a ton of options and is incredible. In all my years of using a personal server to host music, this app has been the best by a lot. As for desktop apps, I don’t use them much, but when I do, I use Musicbee, which also offers unlimited customization if you’re willing to put time into it. It used to have a subsonic plug-in, but I have no idea if it’s still active. I just use the local file location and treat it as its own entity. If the subsonic plug-in still works, it may allow you to do what you want since everything seems possible in Musicbee from my experience.
