I've done the same. You can get some obscure stuff from soulseek if Lidarr isn't finding all the stuff you want. I'm mostly using that and just using Lidarr for organizing and tracking.
You're 100% right about the plexamp DJs. They're super good. Love the deepcuts one.
I'm running deluge in a docker container on unraid and I have this same issue in Firefox but not in Chrome. I also have authentication problems in qBittorrent in Firefox that don't happen in Chrome. It's literally the only thing I use Chrome for unfortunately.
I use a steam deck for about 2/3 of my gaming and I rarely have issues with games. That said, I mostly play indie games, but there is so much of my library that is supported that I'm never going to run out of things to play. Proton has really done wonders for gaming on Linux. Are you wanting to play multiplayer games or brand new releases? Or are you more of the patient gamer type?
I wouldn't run steamos on a full desktop, but you can still get a lot of the benefits just by using steam on Linux. Definitely recommend trying it out.
That's the point. Are you aware of The Satanic Temple and their work on the separation of church and state?
