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.
Been looking for an alternative for iTunes for ages. iTunes runs like hot garbage on my PC, but for me it just seemed like there just wasn’t anything like it for offline music playback an d management. This looks very promising, I’ll definitely check it out. Thanks!
