Amazon (AMZN) is tired of seeing iPhone users go to the iTunes store to download their favorite songs and has decided to revamp its mobile music store specifically for the iPhone and iPod touch. Amazon says the new MP3 store is built on HTML5, “which means customers can make purchases directly from the Amazon MP3 mobile website at on their iPhones and iPod touches” and will give iOS users access to Amazon’s 22 million song catalog. And of course, once you purchase a song from Amazon you can save it to your Cloud Player library so you can listen to it on any of your computers, smartphones or tablets.
