Wireless song sharing is a big part of what Microsoft is using to differentiate it's new player from the iPod and others. But this line in last week's Zune announcement has bloggers buzzing:
"...users can listen to the songs three times over three days before deciding whether to purchase it themselves."
What kind of DRM is Microsoft attaching to a shared song to make this little trick happen? And what happens to a song when it's no longer playable? Does it just take up space on the hard drive?
