Spotify has worked with Amazon Echo since 2016, but only for premium subscribers. Today, that changes as Spotify says its free tier will now stream across Alexa-powered devices, as well as other smart speakers from Sonos and Bose. The Alexa support will be available for users in the U.S., Australia, and New Zealand. Support for Sonos and Bose is more broadly available to users around the world.

In the case of Alexa devices, like Amazon Echo speakers or the Fire TV, users will be able to ask Alexa to play Spotify’s playlist, like “Today’s Top Hits,” or their personalized playlist, “Discover Weekly,” among others. The service can also be set as the default, so you can use commands like “Play my Discover Weekly,” “Like this song,” or “Pause,” and more, without having to say “on Spotify.”
