zune pass

Zune Pass allows you to download 2 types of content, “subscription” content and “purchased” content.  For the monthly fee, Zune Pass allows you unlimited downloads of subscription content, which won’t work with the Fuze because it’s “DRM’d” .wma files, in other words, copy-protected to only work on the Zune.  Even if you copy the files manually to the Fuze, they won’t play.  “Purchased” content is in non-DRM’d .mp3 files, and should work on anything.  Each month you are given free credits enough for 10 songs, and you can also purchase additional credits as well to exchange for songs and videos.  But – not all songs can be purchased this way, some are only available as subscription.

You would get so much more out of a Zune Pass with an actual Zune. 

Hope this helps.
