Using the Sonos/Tidal music service on an iPhone. An artist’s radio will not play properly. 

So I tried using the Sonos/Tidal service on my PC. Used play to choose play now. The artist’s radio plays fine. Then I saved the Queue as a Sonos playlist. And gave it a name. Now It shows up as a Sonos Playlist on my PC without opening Tidal.  

As well, the playlist shows up in the Sonos app on my iPhone as a Sonos  Favourite. Without opening Tidal. Plays fine. 

This is great because I like having a number of playlists on tap depending upon the mood. It is easy to remove a playlist and add a new ones.
