Here I thought the MP3 wars were over. Anyone can buy any album they want online for about $10, or a little more for new releases. That’s the end, right?

No, not according to Amazon. It wants a bigger share of the lucrative iPhone/iPod/iPad market. Apple keeps its customers locked up pretty tight, since it has a simple and effective ecosystem between its mobile devices and the iTunes Store. Amazon is looking to crack that system.

Amazon took a shot this week by optimizing its MP3 store for iOS devices. That means when someone on an Apple device goes to www.amazon.com/mp3, they get an interface. The reason to go is the great deals Amazon offers on select albums. The fun album pictured here currently sells for $3.99 on Amazon, but $9.99 on iTunes.

This isn’t the first time that iOS users could buy tracks from Amazon, but the revised interface makes the process of finding and purchasing music much easier. By selling directly through a web browser and not through an app, Amazon avoids having to pay Apple 30 percent of the purchase price.

When you purchase Amazon songs on an Apple device, you can’t immediately download them to your iTunes library. You instead play them with the Amazon Cloud Player, a free app. The Cloud Player can also play anything in your iTunes library, so if you like it you might want to make it your primary player. Once you’re back at your desktop or notebook computer, you can add those purchased tracks to your regular iTunes library.

All this is good news for music-lovers, since it means more choice and better prices.
