Could someone please explain to me why this is cool/useful? I'm not a huge spotify user. Is the idea that I can set up the daemon on a networked computer in my home and then have it stream to speakers around my house?
Its an unofficial Spotify client for nix-based systems.
I suppose its cool if you run a riced nix environment, and you only want command-line tools. Or its cool for people who don't want to run the dedicated app or browser version.
In my experience, having tried a few different clients in the past, they sometimes fail due to changes on Spotify's side. I don't know if that situation has changed in the past few years.
