Amazon's iOS Cloud Player app, which allows you to play all of the music you've got stored on Amazon's servers in sky has been around for a while, but until now, actually buying a song from Amazon's MP3 Store from your iPhone has been a pain in the tuchus.

Amazon just launched an HTML5 web version of its MP3 store that's "optimized" for iPhone and iPod Touch. We tried it out on Chrome and Safari on an iPhone, and it's fast and slick enough to compete with iTunes. When you head to the same URL on an Android device, you just get Amazon's boring old desktop site. Obviously, this is just a way to get around Apple's App Store approval goons since, you know, you've been able to buy MP3s from the Android version of the Cloud Player app for time immemorial.
