When the Amazon Appstore first launched it was very limited in the number of apps. But thanks to the popularity of the Kindle Fire the Appstore has grown with more Kindle Fire specifics apps showing up everyday. One very popular app that is now available as a Kindle Fire Edition is Spotify. This is the popular music streaming app that came to the US just this year. The app can be downloaded for free and will let you listen to radio music like Pandora without any costs. But if you want even more, then upgrading to a premium user will let you play your own music or stream anything from their library. Basically you can listen to almost any music you want at anytime with sharing options to Facebook. This is a great service and a great app that is now officially on the Kindle Fire.
