Who has any knowledge of Zune's?

Bought one of these as a gift this year for Christmas and I see all of these sites that offer unlimited downloads for a one time membership fee with no monthly payments or payments for each download. How can this NOT be a scam?
If anyone knows anything about Zune's please comment.

Hope everyone had a great Christmas!

There are a lot of free unlimited Zune download sites are riddled with pop-ups, adware and viruses.
