The RIAA has started to put ads in spamfiles
 

They have begun to put promotional material into the decoy files and then sprinkle the files across the P2P networks for people to download. "The concept here is making the peer-to-peer networks work for us," says Jay-Z's attorney, Michael Guido. "While peer-to-peer users are stealing the intellectual property, they are also the active music audience," and "this technology allows us to market back to them."



Jay-Z, at the request of Coca-Cola, is among the first to agree to allow such P2P distribution. His "decoy" contains an eight-minute concert outtake clip mixed in with a promotion for Coca-Cola of course.

I dont get this part

Well I haven't tried downloading it, but I'm guessing mp3 128 Kbps quality or ACC that even gets somehow ruined more by that CocaCola ad.

Of course, I might be wrong. That article is the only info I have on the subject.
