Four American college students learned last week that free music downloads can carry
a hidden price tag-US $ 12,000 to $ 17,500,to be exact.
Major record companies accused the students of fueling music piracy (盗版) by
runningfile-sharingnetworksoncampusallowinghundredsofsongsto be downloaded for free.
Last Thursday,the four promised not to violate the companies'copyrights.Although they
did not admit any wrongdoing,they each agreed to pay thousands of dollars to the Recording
Industry Association of America (RIAA)．
"I don't believe that I did anything wrong," said Daniel Peng at Princeton University,one
of the four."I hope that for the sake of artists,the larger issues can soon be resolved." None
appears to have made any money off the file－sharing systems they operated,which were
confined to their campus's computer networks.
The payments mark the first time record companies have recovered money from
individuals in the US accused of piracy on file－sharing networks.This may be a sign of
things to come,as the industry starts taking its battle against online piracy directly to users.
Many record－company executives blame the long slump in CD sales on file－sharing
networks,which let users copy songs from each other's computers for free.
Matt Oppenheim,senior vice president of business and legal affairs for the RIAA,said the
settlements,although well below what the companies could have asked for,were "the right
amount" given the situation.
He also noted that since the four lawsuits were filed,at least 18 campus file－sharing
networks have been taken down by their operators.
