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 just want winamp in working order.
Audacious has a winamp mode and supports winamp skins.
QMMP supports Winamp skins, that’s what I’m using, it’s fantastic.
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).
