The new integration is available starting Wednesday. Anyone can experience it as long as they have Philips Hue color capable lights, a Hue Bridge, an audio device, and a Spotify account.
Spotify/Philips Hue
Philips Hue notes that you won’t be able to sync with Spotify unless you have a square-shaped Hue Bridge, so even if you have Philips Hue Bluetooth lights, it won't work without the Bridge. However, the syncing experience is available for those who have both free or Premium Spotify accounts.
