It's a paid app with a free trial, so the benefit is the app. I haven't been using it long. My trial just expired and buying was a no brainer. It's a one time purchase for life, amazing deal so far. Absolutely as slick as Spotify/ tidal and way more customizable UI. I listen to music all day and I've never been this pleased with a setup.
It would be nice if it were open source, maybe when the dev stops wanting to maintain it he'll open it up but he's pretty on top of things right now. Can't really complain.
