Spotify is now available on all Play-Fi audio products but the way it works is different from the other streaming services. Instead of Spotify living in the Polk Omni app, the Polk Omni product itself communicates directly with Spotify.
To enable this feature:
1 - Simply download the latest version of a Polk Omni app and allow it to update your Polk Omni product.
2 - Once you're all updated and ready to go, open up your Spotify app and start playing something.
3 -On the Now Playing screen, press the Spotify Connect button, which is the little speaker icon at the bottom of the screen.
You'll then be able to see all the Spotify enabled devices on the network (including your Polk Omni products). The selected products are now tied to your Spotify Premium account and as long as the product can communicate with the Internet, you can play to it from your Spotify app.
