On Google blog they say
“To play music from Apple Music, first link your Apple Music account in the Google Home app. You can also select Apple Music as your default music streaming service. Then, all you have to do is say, “Hey Google, play New Music Daily playlist,” or “Hey Google, play Rap Life playlist.”
You can ask Google Assistant to play any specific song, artist or playlist available on Apple Music, and you can play music based on genre, mood, or activity. You can also play your liked songs from your Apple Music library by saying, “Hey Google, play my songs” or “Hey Google, play my library.” If you have more than one compatible smart speaker or display, you can use our multi-room control feature in the Google Home app or on a Nest smart display to dynamically move your music from one device to the other, and even play music on all of the devices in your home by saying, “Hey Google, play music on all my speakers.”
This Apple Music features roll out to Google Nest and other Assistant-enabled smart speakers and displays starting in the U.S., U.K., France, Germany, and Japan.
