I found this on a dust sleeve of a record "Home Taping Is Killing Music And Is Illegal." I had forgotton that music was often taped onto cassette tapes which were easier and lighter to carry around from house to house and then in the car when we got players in them. Now we have tiny MP3 players or mobile telephones with the facility for music videos !!
We still have problems with music piracy all these years on inspite of loads of free downloads available.!
