Controversial digital-music site MP3.com has been sued for copyright infringement by former Beatles bassist Paul McCartney. In a case filed March 14 in New York, McCartney's MPL Communications publishing company alleges MP3.com violated MPL's rights when it created the My.MP3.com online CD-playback service. The service "is a cynical attempt to exploit the value of famous songs without the copyright owners' consent in order to attract greater 'traffic' to its Web site," the suit charges, according to court papers posted on MP3.com. MPL lawyer Carey Ramos said he could not talk about pending litigation. (Ramos' firm, Paul, Weiss, Rifkind, Wharton & Garrison, also represents SonicNet's parent company, Viacom.) MP3.com did not return calls.
