Amazon announced today that it’s adding support for Spotify and SiriusXM to the multiroom audio feature on Echo devices, letting users synchronize music across multiple rooms. Amazon launched the multiroom audio feature earlier this year, supporting Amazon Music Unlimited, TuneIn, iHeartRadio and Pandora. But now, as Amazon promised back in August, Spotify (and SiriusXM, if that was a deal-breaker for you) will work with multiroom playback, too.

For now, Spotify is only available with multiroom audio on the Echo in the US, UK, Germany, Canada, and Ireland, while SiriusXM is only in the US. But if you’re looking to use Echos to build out your own ad-hoc Sonos-style system, the addition of Spotify support should go a long way toward making that a reality.
