Well, I have to say that Harmonoid is the best one I’ve found, it has a ton of cool features, it works and it allows you to be able to see your collection by album and it doesn’t use Electron. Right now its development has stalled a bit but it’s still pretty much in good shape, though.
I still miss armarok 1.4.10
Is Amarok still a thing? I stopped using players a few years back in favour of Spotify, but I’m considering self hosting a collection again, and I remember Amarok being the best player by far.
