SPOTIFY IMPORTANT

Those who have shuffle playback on their mobile phones must log out and register with a new number or account. This way, Spotify gives them the benefits of a free 14-day Premium account without any subscription, and they can stream just like on a PC/tablet.

It worked for me; now it's like I'm on a PC. It's reliable, and no, it doesn't harm the stream—on the contrary, it's better, so there's less chance of them eavesdropping.
