Devices "steals" my music

[Reiler]

I my home, I have Spotify installed on several devices.

My problem is that while listening to music on my Windows PC in the Spotify app, my music suddently dissapears. This is because someone in my house have turned on a device with my Spotify account on.

I have a bike trainer in my cellar, where I have an Android device that is always pluggede in the power, but the power is only on when the ligths in the cellar is on.

This means that every time someone enters my cellar and turns on the light, the music I am listening to on my Windows PC starts playing in the cellar, and stops on my Window PC 😞

I am old enough to being able to start music manually, so I just want to disable this "feature" that I find very annoying, does anyone kow how to do that?
