When you ask Alexa to play music, it will always try to find the song, artist, album, or station in your Amazon Music Library or on Prime Music unless you append your request with “…on Pandora” or “…on Spotify.” Now you can change which music service is used by Alexa when no service is specified with your request. To do so, load up the Alexa App, select “Settings” from the left side menu, scroll down and select “Music & Media,” and press the “Choose default music service” button at the bottom. You’ll then be given the option to select a default music library other than Amazon, like Spotify, and a default station service other than Amazon, like Pandora or iHeartRadio. The option does not appear to be available through Amazon’s Alexa web portal yet. Changing the default music service will effect all Alexa devices registered to your account. You cannot select the default music service on a per device basis. It’s great to see Amazon giving customers this type of control which opens up their walled garden just a little bit more.
