You don't need to buy a new Echo to get Alexa's best new feature

Amazon just dropped a whole bunch of Alexa-equipped gear on us, including a redesigned Echo speaker with a price tag of just $99. That's a bargain compared to the $189 price of its predecessor, but you can take advantage of Alexa's best new feature on your old Echo stuff right now, for free: Multi-Room Music is rolling out across the platform. Multi-Room Music allows you to play your tunes or talk radio (woo!) simultaneously across a variety of Echo devices on the same network. It works like a Sonos system, pumping audio to individual speakers throughout a house. Or, you can place several speakers around a really big room that's covered by the same network, a technique often used by gyms, studios, or other large spaces.
