Right now on if I ask Google Home for music 'like' an artist, or to 'play [artist] radio', on Spotify Premium it just starts playing the 'This Is [Artist]' playlist, which only contains music by that artist and no others. This is not expected behavior - instead, it should play the radio mix based on that artist, like I can do from within the Spotify app by finding an artist and selecting 'Go to radio'. Note that this is definitely a problem with Spotify, not Google, because the Google Assistant replies 'Playing [artist] radio', even though Spotify doesn't do that (it just plays the artist's playlist).
