I share my Spotify Premium account with my girlfriend. If I now link Discord to Spotify on my laptop (also on my laptop), it will be displayed to the people I'm friends with on Discord when I listen to music on Spotify. I always have Discord running in the background on my laptop, so if I'm not listening to Spotify right now, but my girlfriend (on her phone), will it still be displayed on Discord? So is this only displayed when I listen to Spotify on my laptop, or in general who is listening to Spotify with the account when I have Discord running in the background?
I think it is always displayed
It can be displayed if you have Spotify open while she is listening to music.
Can it also happen if I don't have Spotify open on my laptop?
No
