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 use Sonixd and Feishin. Feishin is the re-write of Sonixd, but only supports Navidrome currently (which is actually what I need; apparently *sonic support is incoming). Sonixd still works though, and is nice.
Never heard of them before, thank you, I’ll be checking them out.
