With the addition of Apple Music, Alexa new features support for several music streaming services such as Amazon Music, Spotify, Tidal, Deezer and Pandora. Depending on your music preferences, you can choose the default music library and music station sources for your Alexa-powered Amazon Echo speaker.
Although you should benefit from all the features Apple Music offers on other smart speakers like the HomePod, it appears that the implementation isn’t 100% complete. As 9to5mac points out, it appears that you can add a song playing on an Apple Music station to your library with Alexa when it’s playing on the Amazon Echo. Also, there’s no way to play music manually added to Apple Music from your own music collection.
For now, Amazon Echo owners must settle for simply listening to the music available on Apple Music or any songs added to their library, and that’s perfectly fine for now.
Keep in mind that if you own an Alexa-powered speaker, other than an Amazon Echo, like a Sonos speaker, you won’t be able to control Apple Music with the digital assistant.
