Then stop making music for free. Find a way to get paid before you put the work in. Because after it's been made and published, it's already over.
Computers exist and are networked. Data is trivially and infinitely copyable. The clock will not be rewound back to the dark ages where data was a finite product that people could buy and sell. No matter how much the music industry rages and sues, it won't change the fact that YouTube is just sending me data via HTTP and there's absolutely nothing they can do if I decide to redirect that data to my hard disk instead. It's up to them to adapt to their new reality. If they can't, that's their problem.
