Record companys should get with the program & realize what game making software companys figured out long ago. Write off the loss, due to piracy & revel in the free press.
It can cost more in "marketing" to create a buzz about a product, than letting the product & the users "create" the buzz.
Case in point, the same year that Napster was starting to be slammed by RIAA, & they were claming such "harm" to their supply chains, they were turning in bumper sales reports..
Why you ask? Billions worth of free press.
It wasn't untill there was suffient public backlash against RIAA, that collective sales went down.
