Go me thinking, wonder how successful it would be if someone like apple wrote a program to determine people pirating music then sent then somehow got in contact to them with a link to buy, like the Microsoft anti piracy strategy with windows. On the whole would probably be more successful than the lawsuit path. Another idea for a service, something that scans a computer for pirated music, lets a user select which albums they would like to buy and offers a big discount.
