The music industry is shooting itself in the foot by trying to stop online file sharing, according to a new Jupiter Media Metrix report. Aram Sinnreich, Jupiter senior analyst, says: "It is safe to say that active usage of online music content is one of the best predictors of increased consumer purchasing. Thus, music sellers should devote their imited resources to online marketing and distribution -- rather than eradicating the phantom threat of file-sharing, if they truly wish to stanch the blood flow and turn the music market around." It is not unusual for media companies to act against their own best interests. For example, the movie studios tried to stop people taping things on their VCRs.
