I like listening to Smooth London radio, always nice and relaxing. However when I used to ask Alexa to play it, it would play some dodgy other Smooth radio station, it could never find this on TuneIN.
I managed to get this to play by enabling the Skill "RadioPlayer", this found it first time, so now I just ask Alexa is play radioPlayer and it picks it up.
So maybe if Alexa can't find a station you are looking for, then look at RadioPlayer.
UPDATE - 20th November - Smooth is now available on TuneIn, however still work looking into this just incase your favourite station isn't on there.
