Radio Paradise, music playing is not what is displayed

It usually wokrs quite nicely, but it was explained previously that somehow two streams (one metadata, one music) is merged in Roon with the aid of some external service?
I think Alec_Eiffel was involved here, somehow?
Anyways, there’s an old feature request, for “better” integration but it has mostly been covered today:
Add Radio Paradise as a “music service” - Feedback / Feature Suggestions - Roon Labs Community
