And there's a super-cheap Echo-only plan too.

As rumored, Amazon has finally unveiled its new streaming service, dubbed Amazon Music Unlimited. Like rival services, the regular price is $9.99 per month, but if you're an Amazon Prime member you'll only pay $7.99 per month (or $79.99 annually.) Subscribers get access to "tens of millions of songs," a step up from the more limited selection offered through Amazon Music to Prime members.

Alexa and Amazon Echo are a big part of the company's new streaming service, with a cheaper $3.99 subscription giving you access just through Amazon's smart home speaker. And similar to Google Home, Alexa's natural language processing can help it find the track you're after, even if you don't refer to it by name — matching music by mood, release date, or lyrics.

The move sees Amazon looking to capitalize on its lead in the connected home, before the launch of Google's rival products later in the year. Amazon has a long history in the digital music business, and Echo integration will will give it a very unique differentiator — at least for the next few months.

The service is live in the U.S. right now. It'll launch in the UK, Germany and Austria later in the year. In addition to the standard personal subscriptions, a family plan will be launching soon for $14.99 per month (or $149.99 yearly), allowing you to share your subscription with up to six people.
