Microsoft just added one million new DRM-free tracks to its Zune Marketplace online store, according to Download Squad. This comes as Microsoft updates its Zune player and adds a smaller, flash-based version to the line-up in order to better compete with Apple's iPod line.

Microsoft also removed the three-day listening limit to shared music between Zunes. Unfortunately, you can still listen to a shared track just three times before it self-destructs, Mission-Impossible style. Check out the link below for more updates on the Zune--it looks like Microsoft is getting serious about the portable MP3 player market.
