Google today announced a small but nifty feature for the Google Assistant and its smart home devices that makes it easier for you to take your music and videos with you as you wander about the different rooms in your home.

“Stream transfer,” as Google prosaically calls it, allows you to simply ask the Assistant to move your music to a different speaker, or — if you have the right speaker group set up — to all speakers and TVs in your home. All you have to say is “Hey Google, move the music to the bedroom speaker,” for example. In addition to your voice, you also can use the Google Home app or the touchscreen on your Google Nest Home Hub.

This will work with any source that can play to your Chromecast-enabled speakers and displays.

It’s all pretty straightforward — to the point where I’m surprised it took so long for Google to enable a feature like this. But maybe it just needed to have enough devices in peoples’ homes to make it worthwhile. “Now that millions of users have multiple TVs, smart speakers and smart displays (some in every room!) we wanted to make it easy for people to control their media as they moved from room to room,” Google itself explains in today’s announcement.
