If it is always a pleasure to get free things and gifts, Microsoft might not really appreciate information lying in music track tags:
As illustrated above, those free music tracks have been encoded with iTunes 6.0.4, and not by MS own audio solutions.
Of course, one should always use the best tool, but if Microsoft starts using Apple's solutions to promote the Zune, we are not sure about the real success/future of the Zune in USA, as in Europe.
