My Question or Issue

Spotify is spontaneously casting on my chromecast, starting my receiver and my tv in the process. There is just the big SPOTIFY label on the tv and nothing is actually playing. It already kind of burned into my old plasma tv, as only God knows when Spotify decides to start casting on its own and I am not around to stop it. It is a real nuisance.

I thought it triggers when I grab my phone and unlock it but at times it starts even completely on its own. I turned some of the Spotify features off but it didn't help. I am considering leaving Spotify if this persists. Please help.
