Swan Song For Music Swaps?

Napster may be dead, but the forces that felled it have lots of fight left in them. Three major entertainment-industry groups made another push last week in their campaign to zap illegal file sharing on Web sites Kazaa, Grokster, and Morpheus.

The Recording Industry Association of America, the Motion Picture Association of America, and the National Music Publishers Association are seeking a summary judgment in their suit against the alleged copyright infringers. They want to force the file-sharing services to block illegal sharing of copyrighted materials, while the services say they're not responsible for their users' behavior.

The industry groups were probably still pumped from their total victory over Napster, the granddaddy of free-music sites, which turned off the music two weeks ago. At the same time, their filing also served to answer Judge Stephen Wilson's call to speed up the litigation.
