@sec.SSa Sorry for the slow reply and welcome to the Sonos Community. I understand that you describe content no longer available with TuneIn. Please confirm that these stations are not available with I Heart Radio or other streaming service. Please know that with TuneIn, if you have the radio stations streaming URL you can add them into Sonos from a computer and still play them on your Sonos system.

Install radio.net as a music service.

Those stations are all there.

I have had this exact problem. FIP Radio was working really well including all their Pop, New, World etc stations. Recently the main FIP station quit working but the rest would work. Today, none of them work. The FIP app works just fine on my iPhone, but having a Play:1 there isn’t any Airplay capability available. 
No French stations whatsoever are available on TuneIn, so what are we supposed to do to get foreign broadcasts??

Read the post before yours.

(TuneIn lost a court case over linking to stations unlicensed in the UK.  Maybe radio.net will have to follow suit though?)

You’re a star. Thanks! Working now!
