It may be duking it out with Apple over rights to the "app store" name, but Internet retail giant Amazon has, nevertheless, optimized its flagship MP3 store specifically for the Cupertino company's iPhone and iPod devices.

Amazon's browser-based Amazon MP3 Store has been optimized for Safari on the iPhone and iPod touch to cleverly side-step native iOS app restrictions and its 30 percent fee structure for in-app purchases.

"Since the launch of the Amazon Cloud Player app for iPhone and iPod Touch, a top request from customers has been the ability to buy music from Amazon right from their devices," said Steve Boom, vice president of Amazon Music in a press release.. "For the first time ever, iOS users have a way do that-now they can access Amazon's huge catalog of music, features like personalized recommendations....They can buy their music once and use it everywhere."

The MP3 store will be directly availble to iPhone and iPod owners through the Safari browser, giving access to Amazon's catalog of over 22 million songs.

Amazon says Apple customers using its MP3 store will have full access to features such as personalized recommendations, best-seller lists and ratings, as well as have the ability to save their music to Amazon's Cloud Player libraries which can be downloaded or played instantly from any iPhone, iPod touch, iPad, Kindle Fire, Android phone or tablet, Roku, Sonos home entertainment system, or any Web browser.

Amazon has been pushing hard to compete with content providers such as Apple, Netflix, Google and Barnes & Noble in everything from e-readers to the music business. Last month, the company released an instant-video app that would allow users to stream or download Amazon Instant Video movies and TV episodes from their video library directly on their iPhone or iPod touch.
