Free iTunes song downloads by joining Facebook group.

I found a ticketmaster facebook promotion today. It invites web surfers
to join the Ticketmaster group on Facebook - http://www.facebook.com/group.php?gid=2426357824

After joining, the user be given an iTunes code valid for 5 free song downloads.
After you receive the code, you can leave the group right away. The coupon codes expire November 15 so you need to use them right away.
