Not today but we're planning some radical changes to the music data we rely upon which should open it up to Apple Music, Deezer and beyond!
IMHO, this is exactly the sort of functionality I'd expect to be built into any music service when I say "start song radio". They misuse the word "radio" by so many degrees, they just mean "shuffle".
Even if it's not broadcast over actual radio, at least give me an announcer! And you've done that, and I'm very intrigued. Is there a place I can sign up for reminders to learn when the Deezer connector is ready?
