Amazon Music has recently announced the testing of Maestro, an AI-powered playlist generator, allowing U.S. customers on both iOS and Android to create playlists using spoken or written prompts. This move follows Spotify’s launch of its own AI-generated playlists in the U.K. and Australia.

Maestro is currently available to a subset of free Amazon Music users, Prime customers, and Amazon Music Unlimited subscribers in the U.S. The product is launching in beta, with Amazon warning that the technology may not always get it right the first time. To ensure a safe and appropriate experience, Amazon has added guardrails to block offensive language and inappropriate prompts.

Subscribers to Amazon Music Unlimited will have access to more functionality, such as instant listening and saving playlists, while Prime members and ad-supported users will only be able to listen to 30-second previews of the songs before saving them. This could potentially encourage more users to upgrade to the paid subscription if they enjoy the AI functionality.

To access Maestro, users will need the latest version of the Amazon Music mobile app and can tap on the option for Maestro on their home screen or when creating a new playlist. They can then either speak or write out their playlist prompt idea and tap “Let’s go!” to start streaming it. The playlist can also be saved and shared with friends.

Amazon suggests prompts like “crying and eating spaghetti,” “make my baby a genius,” “Myspace era hip-hop,” “desert and cactus and cowboy,” “music my grandparents made out to,” “singing in the shower,” and “I tracked my friends and they’re all hanging out without me” to give users an idea of how silly the prompts can be for this new experience.

Amazon did not provide a timeline for when the beta would roll out more broadly, only stating that it would expand to more customers over time.
