How to play internet radio stations in the Music app on iOS 13? I read several posts, that it should be possible to listen to internet radio stations from TuneIn in Apple Music (e.g. https://www.audioxpress.com/news/tunein-and-apple-bring-the-world-s-radio-stations-to-apple-music-and-all-siri-enabled-devices). But It does not work for me - neither Siri (language: German) nor typed search for radio stations yields any result. 

My question: how can I listen to internet radio stations (e.g. hr3, srf3, ...) using Music on iOS 13? I have an Apple Music subscription.

If it is relevant: I am in Switzerland.
My guess is that it has something to do with your location. I'm in the USA and when I searched for "hr3" in the Music app it immediately showed that station you are looking for as a result. Maybe TuneIn only works with the Apple Music app in some countries?
