These days, you almost can’t get away from hearing music without charge. It is playing in every restaurant, bar, coffee shop, grocery store, and retail shop you go into. Technology has made it possible to hear music of every style everywhere. With all this music literally floating in the air, it is easy to get conditioned to the idea that music is omnipresent, like air, or tap water. No one pays for air (they do pay for bottled water).
