Five years after after Amazon launched the Music Store, Amazon has announced that it has optimized its MP3 music store specifically for Safari on iOS devices to challenge the iTunes Store. iPhone and iPod touch users can discover and buy digital music from Amazon’s 22-million song catalog using the Safari browser.

“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. 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, deals like albums for $5, songs for $0.69, and they can buy their music once and use it everywhere,” said Steve Boom, Vice President of Amazon Music.

Features of the Amazon MP3 store on the mobile web browser include:

– The Amazon MP3 mobile website for iPhone and iPod touches is built on HTML5, which means customers can make purchases directly from the Amazon MP3 mobile website at www.amazon.com/mp3 on their iPhones and iPod touches
– Selection of over 22 million songs and over two million albums at everyday low prices
– Access to everyday deals like $5 albums, $0.69 songs, and free songs from artists on the rise
– Individualized recommendations based on purchase history
– Immediate availability and seamless playback of purchases in the Amazon Cloud Player app
– Free storage of all Amazon MP3 purchases in Amazon Cloud Player
