This is another Home function that is not new, this has been available for quite a while; but may be helpful to those that are not aware or just setting up Home devices. You can use the Home app on your phone to create Groups and link multiple Home devices together so music (or other audio) plays on all grouped devices simultaneously. From the Google Support page: "Group any combination of Google Home devices, Chromecast devices and speakers with Chromecast Built-In together for synchronous music throughout the home."
