This happens on Samsung Galaxy S8. No matter where I listen to music to or how, Spotify opens on my phone, as well as every other device I have that has Spotify on it. I DO NOT WANT TO LISTEN TO SPOTIFY ON ALL DEVICES POSSIBLE I JUST WANT TO LISTEN TO A SONG ON THE DEVICE I ASKED FOR SPOTIFY ON. I just want a simple option to turn this INTRUSIVE feature off. I'm downloading albums I care about now and then cancelling my premium. 

Spotify, all I want you to do is play music. You don't have to do any social networking, you don't have to anticipate what I want to play next, you don't have to **bleep**ING START WITH MY COMPUTER ON EVERY NEW INSTALL AND UPDATE UNTIL I TURN IT OFF, and you don't need to try and sync to all of my devices.

JUST **bleep**ING PLAY MUSIC.
