Added Audials Play app

Sonos adds people who add themselves to the Sonos universe. You may want to point Audials to the Sonos partners page. Audials may enjoy your feedback on their own app, as well. 

This app should be offered by Sonos; it's terrible.

It seems strange to me that you want to add what you say is a terrible app? Or do you mean you think that the Sonos app is terrible? 

It’s the App Audials Play is terrible.
I’d like that sonos support that App L-like others apps : Tunein, MyTuner Radio, ...

Could you explain what Audials does and what the benefit would be to other Sonos users?

By the way, it is up to a service to connect to Sonos. Did you ask Audials?
