Playing radio station via Google Home *for Spotify Premium users*

[xmasmoneky]

According to Google Home's help documentation:

• If you are a Spotify Free user - you will always end up playing a station based on the song/artist/album you ask for.
• If you are a Spotify Premium user - you will always end up playing the exact song/artist/album you ask for.

My question is - if you are a Premium user - how can you play a station based on the song/artist/album?  I.e. I want the ability to both play exact songs/artists/albums, as well as the ability to instead play a station based on my choice.
