The music is fine but the app is almost unusable. The controls disappear from the lock screen and top pulldown constantly, and when listening to an album or playlist, it will suddenly revert to that song's radio (or whatever the Tidal equivalent is called). The app frequently just shuts down. They also do not have a feature to control the app on another device. Other things aside, Spotify is just so much better functionally that I might go back. I'm sad, I really wanted to love this app.
