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 tried qmmp a while ago and it is unusable for me because it doesn’t have the library view that winamp had (at least that I could find).
