As for the music industry I remember just 10 years ago a CD single costing anywhere from £1.99 to when it came out to £4.49 when it was in the charts, now you can get them for around 29p to 49p.
As for Gaming, you really think that someone that has a dodgy DS or Wii and has 50 games for it really was going to out and spend £30 a game on 50 games? they are only getting it as its free to a maximum couple of quid.
Obviously you would expect them to go out and buy 1 or 2, but not 50.
I in no way Condone, recommend or have any items relating to the above illegal activities.
