Pricing for Music Unlimited will vary by area, but Amazon says it'll offer the same three plans it currently does -- including an Echo-only plan, the standard individual plan for smartphones, computers and other devices and a family plan for multiple users. Amazon's also not discussing pricing for Echo hardware, as that also will vary from country to country. But launching both the hardware and service at the same time is a smart move, as the company says its music service is designed with voice control in mind. Of course, Spotify and the like work just as well, but having both the Echo and Music Unlimited available at the same time will ensure new customers can use their new speakers to their fullest extent.
