If you have an account that's not premium, this prevents you from logging in (also the website covers the login button with a banner ad, so you have to log in by passing through the terms & conditions page). The app also doesn't recognize when you DO sign up for a paid account. The shuffle feature and the queue both turn the other off. It forgets genre preferences regularly. This is scratching the surface of how bad the app is. But there's a good selection of music, that plays at good quality.
