Amazon's Prime Music streaming service is now available in the U.K., just over a year after it debuted in the United States. Just like Prime Video, the service is totally free to Amazon Prime subscribers.

Prime is already incredible value for money at just £79 (approx. $124) per year in the U.K., and Amazon continues to throw in added extras that make it even greater. Subscribers enjoy free next-day delivery, Prime Video, unlimited photo storage, over 500,000 ebooks — and now Prime Music.

In the U.S., Prime Music already boasts more users than Tidal, Deezer, Rdio, Rhapsody, and Google Play Music combined, according to The Guardian, but its music catalog has some catching up to do. While Apple Music and Spotify offer around 30 million tracks, Amazon offers just 1 million.

But Paul Firth, head of music for Amazon U.K., believes "the best music streaming service is the one you already have" — and that's Prime Music if you're a Prime subscriber.

Prime Music is available on Android and iOS devices, including Amazon's own Fire phone and tablets. Users are able to store tracks locally for offline listening, and users who have previously purchased MP3 and CDs from Amazon will find that music available in their library.

If you haven't subscribed to Amazon Prime before, you can take advantage of the company's free 30-day trial before you commit to the £79 annual fee.
