Thanks for the clarification, @Clive_Gidney!
Currently our Radio feature is limited only to content that is in your library, whether it be local media or TIDAL content you have added. I’d like to recommend adding your voice to this Feature Request thread as our product and DEV team keep a close eye on this category. That’s definitely the best place to propose a change like this and get feedback from the Community.
Our CTO made a post about the “radio” function in Roon earlier this year which includes a lot of information about how Radio works and what we’d like to see in the future which can be found here.
Thanks,
Dylan
