Sonos has enabled the ability to play music from Spotify on its speakers using Amazon Alexa..
To enable this feature users must select Spotify as the preferred music service inside the Alexa app. Alexa can then be told to play songs, albums, artists, and playlists from Spotify.
The update is an improvement to the Sonos One smart speaker which features integrated Alexa; as well as, upcoming support for Google Assistant and AirPlay 2. Previously, you had to start playback from the Sonos or Spotify app.
The new feature can also be used by owners of Amazon Echo, Echo Dot, and other Alexa devices to launch playback of Spotify music on their Sonos speakers.
