Spotify and Apple music are not currently supported, but Amazon Music, TuneIn, IHeartRadio, Audible, Pandora, Gimme Radio, Deezer, and SiriusXM are all supported! 

To add these, set them up in the Alexa app under More > Settings > Alexa Preferences > Music & Podcasts. We are working with Spotify to get certified to use their service and as soon as possible. All Dopplers will be upgraded to use the new features when they are ready.
