It is plain stealing but many do it, so that makes it OK

The studios, the music publishers and the authorities are now trying to change it. In Sweden the biggest outfit Pirate Bay got convicted, in France the Gov. is cracking down with a new "three strikes" law, in UK a new law is being prepared and in Germany the ISPs have recently been forced by the courts to reveal IPs of individuals who upload or download pirated material to the police. It will not be long before even the FBI comes calling at people homes. They are using the same software used to track down pedophiles. However in the US there are still a few court challenges pending so it may be a while before the cops come knocking as the do in Germany.
