Affiliate Marketing Secrets

affiliate network, limewire

So for christmas I am torn between a Zune or Ipod. I really like Ipods however I am not willing to pay a dollar per song! First question is can I use a program like limewire to get songs onto my Ipod or not? Also are there any additonal charges w/ an Ipod touch? For example internet etc? On the Zune I want to know if I can only get songs through Zune’s store also (charges affiliated too).
