Amazon’s Echo smart speakers already support a variety of music services, including Spotify, Pandora, iHeartRadio, and TuneIn. And starting on December 17th, Apple Music will join this little cohort.

Apple Music users will be able to ask Alexa to play their favorite songs, artists, and albums, as well as any of the streaming service’s curated playlists and radio stations. Echo owners will simply need to enable the Apple Music skill in the Alexa app, link their account, and they’ll be good to go.
