I have Jellyfin installed on my homeserver, works great for listening to music in my opinion. I sometimes use Bandcamp to find and buy/download music, which I then upload to Jellyfin.

I’ve been using EndeavourOS for a little over a year, and I am very pleased with my experience so far. The only issue I’ve encountered was a GRUB problem, which I had to fix manually using the terminal.
