Napster should get common carrier status, and should not have to attempt to monitor its users to detect law-breaking (which incidentially it cannot do).
Napster allows people to collect their music collections across great distances and this creates such possibilities for crime (copyright violations). They should be forced to try and make sure that crime (copyright violations) isn't possible while operating their service.
ATT allows people to collect their conversations across great distances, and because there is a danger of criminal speech (hate speech, treason, slander) the carrier (ATT) should have to take responsibility of preventing these specific kinds of speech while running the service.
