Among the products and services that online retailer Amazon offers, you can now add a streaming music service to that list. The service that was nothing more than a rumor is now a reality. Amazon Prime Music is the latest benefit to Prime members. Prime members currently enjoy two day shipping and instant videos. Amazon Prime music is now available to customers in the United States and is currently available via primemusic.com or via the latest update to the Amazon Music app via iTunes and Google Play; Kindle Fire HD/HDX devices will receive access via an automatic, over-the-air update. If you are not a member, you can try the service free for 30 days here.
