In case you have an Amazon Prime membership, the retail giant has just added access to the company’s new music streaming service Prime Music. Similar in concept to music services like Spotify or Beats Music, Prime Music provides access to approximately 1 million tracks from both Warner Music Group and Sony Music. However, competing services that charge a monthly fee for subscription offer about 20 million tracks.

Albums included in on Prime Music are from artists such as Justin Timberlake, Pink, Bruno Mars, Blake Shelton, The Lumineers, Bruce Springsteen, and Madonna. Amazon has also created a number of pre-selected playlists that offer up music related to a specific theme. Customers can also create their own playlists to queue up on a mobile device like a smartphone or tablet.

Similar to Amazon Instant Video, Prime subscribers can download entire albums or playlists to listen to when offline. This is a particularly useful feature when traveling on a plane, basically any area where Wi-Fi access is limited.

If you aren’t an Amazon Prime subscriber, Amazon is providing free access for an initial 30-day period. After that point, you would have to pay the $99-per-year fee for Amazon Prime. Beyond the new music service, Amazon Prime also includes 2-day shipping on all qualifying purchases, access to thousands of movies and television shows on Amazon Instant Video (including a huge selection of HBO content added last month) and a book rental each month using the Kindle Lending Library. You can read more about why we think Amazon Prime is a good deal here.

Also, be on the lookout for more perks when Amazon launches their new 3D smartphone next week. It’s highly likely that Amazon Prime membership will be wrapped into the product in some form.
