Sonos partners with TuneIn and other streaming services to provide more radio station options on Sonos Radio.

From Sonos:

“Sonos Radio is the premiere radio experience, only on Sonos. Built for and inspired by Sonos customers, Sonos Radio represents the broadest selection of radio available around the world, bringing together more than 60,000 broadcast radio stations from long-time partners along with dozens of exclusive original stations from Sonos.”

Hmmmm. Perhaps, although I am finding that if I delete a Sonos Radio station that’s giving me the TuneIn identifier and advert and then reselect it via Sonos Radio that the issue I’ve identified is gone.
