The internet, social networking sites and file sharing combined makes record companies obsolete as artists can sell their product directly to the customer. The RIAA is probably more motivated in preventing this from happening then actually "stopping piracy". But as with any industry, you need to adapt or die and it can't be stopped. Unless you actually tried to control everyone's internet by filtering everyone's content and even then if its mandatory government filtering the power is still in the people's hands to change the filiters so it would have to be purely in the hands of big business and it would have to be standard within the individual's computer because otherwise you could easily bypass it with encryption...but that's just crazy lol right?
