Yes, through Bluetooth restreaming. Tracks made available offline in Apple Music are DRM protected and are not playable in the Harman Kardon Controller app. To play these tracks, or any other Apple Music tracks, first connect to any Omni speaker via Bluetooth and then restream to the other Omni speakers in your house with the Link button, or by grouping different rooms in the Controller app. We are looking into the possibility of adding direct support for Apple Music, so check back for updates.
