This actually works. I just finished my offers the other day and my iPod is on the way. It's actually really cool. I don't exactly know how it all works. There aren't any strings or anything that I've been able to spot. I got five friends to join and I joined BMG music (which rocks because I was totally going to join them anyways) and now I get a free iPod. All is right with the world. Here's the link in case anyone wants to check it out.
I apologize to those of you who think this is spam or whatnot. It's something that's way cool though so I wanted to share it. ::braces self for flames from people who'll get pissy over me posting this:: Fire away!
EDIT: if any of you are wary or anything, go ahead and post me and I'll tell you about it and stuff.
