The Recording Industry Association of America (RIAA), on behalf of its member companies, announced a new round of copyright infringement lawsuits against 750 individuals.

The "John Doe" lawsuits filed cite individuals for illegally distributing copyrighted music on the Internet via unauthorized peer-to-peer services such as LimeWire and Kazaa. In addition to the new "John Doe" litigations, the major music companies filed lawsuits earlier this month against 210 named defendants in Arizona, California, Georgia, Illinois, Michigan, New Jersey, New York, Pennsylvania, Texas, Virginia, Washington, and Wisconsin.

"For legal online services to continue to break new ground, we must do our part to protect the integrity of the marketplace," said Cary Sherman, President, RIAA. "Just as we continue to educate fans about the right ways to enjoy music online, we will continue to enforce our rights through the legal system. Songlifting is not without consequences."
