Currently, with an Amazon Echo device, Spotify can only be set as the default "music library". It would be great to be able to set it as the default "Station Service" and tie into the radio functionality. Eg: "Alexa, play XX Artist/Song radio" and it would play a radio station on that artist/song thru Spotify.
