Following Metallica’s delivery of the names of 317,377 Napster users accused of copyright infringement, Napster has disabled the accounts of the named users.

The company said: "We intend to fully comply with the Digital Millennium Copyright Act (DMCA) and our policies. We will take down all users Metallica has alleged, under penalty of perjury, to be infringing."

The company states that the DMCA does offer rights to users – a user banned from the service can be reinstated if they have been named in error. If a barred user attempts to use Napster’s software, the user is directed to an infringement notification page.

Napster also says: "Because of the methods employed by Metallica in assembling its list of usernames, it is possible that users have been mistakenly implicated as infringing the copyrights of songs and recordings originally included on commercially released Metallica albums."

The company promises to reinstate all users incorrectly identified by the band.

MP3.com meanwhile, attempting to ease its relationship with the Recording Industry Association of America (RIAA), has frozen some of the albums stored on its site, so they can be seen, but, literally – not heard.

A message on MP3.com’s Web site says: "On April 28, 2000, US District Court Judge Jed Rakoff granted the major record labels' motion of partial summary judgement. Although we disagree with the decision, we respect the process. As a result, we are voluntarily removing the CDs in dispute from My.MP3.com."

The note continues: "The fact that you are still able to enjoy your My.MP3.com account demonstrates that we are still pushing the technical envelope. We are providing the security any copyright holder would expect on the net, while balancing the desires of consumers to seamlessly interact with their music. That said, MP3.com is vigorously pursuing both a settlement of the copyright-infringement claims, and an ongoing license agreement with all the major labels."
