Microsoft is smarter than we think. If you've noticed they have a pretty attractive suite to go with the Zune which eliminates DRM problems at a relatively cheap price. With a Zune and $15/month you have easy unlimited music that practically never expires and re-attains licenses easily.
Although I would have never bought a Zune, I have a Zune because they gave me one for free when they tried to get me to accept their job offer.
