It's official: record companies don't like you. After all that griping about signing up for the Zune music store -- and keep in mind that these record companies receive monies for selling songs here -- that resulted in Universal Music Group getting some sort of fat royalty check from Microsoft for Zune sales, not to mention whatever negotiations went on behind closed doors to come up with that ridiculously minimal "three days or three plays" sharing scheme, a couple of labels have once again gone out of their way to make life hard on you. It appears Sony Music and Universal Music Group are marking certain artists of theirs as "prohibited" for sharing, meaning that just because you've paid for a song, and even managed to find another Zune user on the planet Earth, doesn't mean you'll necessarily get to beam that JoJo track to another Zune via WiFi magics. In a non-scientific sampling of popular artists by Zunerama and Zune Thoughts, it looks like it's roughly 40-50 percent of artist that fall under this prohibited banner, and the worst news is that there's no warning that a song might be unsharable until you actually try to send it and fail. Oh well, maybe you can just hum a few bars or something -- just make sure the labels don't hear you![Via ClicZune Read - Zunerama Read - Zune Thoughts
