Zune-to-Zune sharing is of limited value with its three play max on shared songs but it is a good way to discover new music (and kind of fun). It seems like something music labels would drool about: people who love the music so much that they actively recommend it to their friends. Zune-to-Zune sharing with its three play limit seems like a perfect fit.
And yet Sony and Universal Music are refusing to allow a whole bunch of their artists’ work from being shared Zune to Zune. They keep digging their own graves and yet they just don’t seem to get it.
