Guest.thurg, that's a pretty sweeping generalization about the motivations behind "most of these pop/rock stars who wrote songs." That many of them made lots of money is undeniable, but that most of them wrote such songs for the express purpose of making money in the first place....wellllll......

Do you have a special psychic beam into the brains of "most of these pop/rock stars who wrote songs" and who do not necessarily own the rights to their own songs now, or who own their songs but may have changed their attitudes over the years, or who have more children/former spouses/current spouse/dope dealers/social causes or what-have-you to support now than they did back when they wrote the songs?
