If they do collect those analytics, which I guess most hosts do by default, you should see some from Poland. Maybe Ukraine too. I tapered off around minute 14 because repetitive music = me drowsy, and I can't go to sleep now.
So the proxy the radio station uses is "do people donate a lot during your timeslot" and "what's the streaming count."
Yeah, I kinda got turned off from current livestream by the twitch-grade "let's drop everything to shout-out donations" focus. The one radio I listen to has a patreon, though, so maybe it's those damn times changing again.
