This is touched on in the article, but the problem is that the artists dont benefit from this. It reveals a fundamental problem with the music industry. The creative people are often taken advantage of and have their royalty rights stripped from them when they are "young and naive" about the music business. The top 5-10% of artists usually find a way to renegotiate once they are a proven profit center, but the artists that do just well enough to keep a deal and dont have their publishing rights end up bankrupt and screwed should their work prove to be "classic".
