Music itself is largely a social parasite that feeds on various cognitive triggers for opportunities or rewards. It is much like a masturbation device used to trigger sexual reward mechanisms. At its best, music relieves frustrations.
I only say largely, as music also has social functions, akin to giving a masturbation device as a gift to others, or using a masturbation device in group sessions to further social cohesion. Only coincidentally, music concerts are more popular than "jackathons".
Going further with the analogy, music industry is not very different from porn industry, neither in how it abuses people's primitive reactions, nor in its ruthlesness. And to say that music industry is just as dependent on musicians, like Albini, as porn industry is on porn stars. They are free to do something else, but they choose not to.
