This app liberated my music from global companies and put it back under my own control and personalisation. I'm not dependent on their storage or app changes that restrict how I play my own music. It also works across devices and means my music isn't stuck on one device or place. For the small cost, I can stream losslessly wherever I am with perfect sound quality. I have over 130,000 tracks in my library and it works wonderfully, with my own genres, playlists, starred selections and app appearance.
