This is one of most interesting reads I read on the net,  Basically music piracy has around before the Napster scene, Pretty much music piracy has been around dated since the 70's when boarder restrictions had strict immigration laws for Germans to crossover to west Germany expect for anyone that was 65 years or older, Back than rock radio was very big in Germany and people from the East could get the signal from West Germany So that only way that they can get is by having Grandma to to Crossover the board to get the a Heavy Metal albums for there grand kids.

As fun an adventures for the teens back then for there Grandmas to get them their favorite Heavy Metal from bands from West Germany.  Please this is a must read!
