Comcast has just confirmed it has come to an agreement with Amazon for the distribution of its music streaming service through its Xfinity X1 set-top box. The move is not a total surprise considering Comcast added Amazon Prime Video to the X1 series early this year.

Amazon Music will be rolled out to Xfinity X1 in the coming weeks and will be available for free to Prime members. The service provides access to more than 2 million songs and thousands of playlists and stations. However, for on-demand access to over 50 million songs and even more playlists and stations through the Amazon Music Unlimited, you’ll have to pay $9.99 per month.

Amazon Music has fierce competition on Xfinity X1, as other streaming music services like YouTube Music, Pandora, and iHeartRadio have been available on the platform for quite a while. Surprisingly, Spotify and Apple Music, some of the most popular services are missing from Comcast’s offering for the moment.

The deal between the two companies mentions that Amazon Music will also be available through Comcast’s Flex service, which costs $5 per month per set-top box. In order to access Amazon Music on Comcast’s Xfinity X1 and Flex, simply say “Amazon Music” into the voice remote and you’ll soon be able to browse and listen to your favorite songs.

Keep in mind though that you absolutely must own an Amazon Prime or Amazon Music Unlimited subscription to access the app on the Xfinity X1 set-top box. You’ll also have to pair your Amazon Music account regardless of whether or not you’re logged in to the Prime Video app on X1.
