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.
Need to make the switch, still using clementine.
For Viz I like projectM (clone of the old MilkDrop), available through Steam.
