They seem to be very stupid. They seem to work very differently from everyone else in marketing, advertising etc. Everyone else works on the assumption that publicity is good; exposure is good. If someone creates a musical jingle for their product, and hear children singing it in the playground, they think "Great! Job done!" They don't think "Nooo!!! It's infringing my copyright." Companies pay lots of money to get their brand of breakfast cereal featured in the background in a movie. The music industry wants the movie to pay them for the privilege of using their song. The cereal manufacturers know that having their product used in a film will boost sales, but the music people don't seem to have realised this rather obvious fact.
