This is zerious.

Microsoft’s insistence on welcoming you to the social isn’t all that neighborly after all. You’re supposedly able to wirelessly share music (well, at least for three days or three plays, whichever comes first) with other Zune owners, but it’s been discovered that over 40% of music tested refuse to squirt because of DRM.

Testing going on with Zune-centric zites sites (sorry, I’m trying to stop, but I can’t help it) like ZuneThoughts and Zunerama have revealed that a lot of music refuse to squirt over to other Zunes despite assurances from Microsoft that you can.

Particularly uncooperative are songs from Sony and Universal, with artists like JoJo, Gwen Stefani, Beyonce, Eminem, Snow Patrol, Ciara, Jay-Z and more.

Imagine working up the nerve, scooting over to a babe with a Zune (that such a creature would exist is possible, but not probable – bear with me) at Starbucks and saying, hey, I got this great Eminem song, you want a copy? and then failing miserably like the loser nerd you are.

Not very sociable, ain’t it?
