Spotify has long offered an app for Android tablets and phones on the Google Play store, but Kindle Fire owners have been excluded from the party — until now. Amazon and Spotify have added a Kindle Fire version of the app to the Amazon App Store, giving Fire owners access to the standard fleet of Spotify features like offline listening, Facebook integration, and access to the service's huge catalog of songs — assuming you're signed up for the $9.99 per month Spotify Premium service. However, users who aren't will still get access to the unlimited, ad-sponsored radio feature that came to the official Android app last week. While we're glad to see this app come to the Kindle Fire, it's rather surprising that it took a good nine months — but fortunately for Amazon, Spotify access is now one less advantage the Nexus 7 has over its offering.
