Kadoink!!

So I've just ran into this very cool little thing that lets people share music for free. And for some reason it's legal (as far as I know). It's called Kadoink and it lets you share music with your friends over the phone. You just record a message to your buds and it calls their numbers with the message you've just created and the song you want to share. I might just be a big dork but I think it's pretty cool. I've got it set up on the Interact Page if you guys want to check it out. The only thing that's a negative is that the sound quality for some reason is a bit rough. Let me know what you guys think of this.
