Gee, what makes them think Joe user is going to start buying more Major Label music when all it supports is more lawsuits. They'll sue until they finally collapse into the pit of hell they came from, taking down as many victims with them as possible.
It is odd though that so many people still haven't learned not to share there files. It's certainly not worth getting sued over, unless your well endowed enough to fight back. Leave the sharing to the countries that still believe in privacy and user rights.
As a side note, I found an interesting comparison of the number of songs purchased from iTunes compared to amount of iPods sold at
http://www.itunesperipod.com. Obviously it's not completely accurate (which they do mention in the statement at the bottom) but it does give you an idea of how many people still refuse to support a corrupt industry. Also worth taking note is the diagram at the bottom about an alternative way to license p2p use.
