NEW YORK (CNNMoney.com) - Napster, the online music service company, said Monday it would offer listeners the chance to listen to more than two 2 million songs for free through a new, ad-supported Web site.

The company said its new free music feature would only be available within the United States at first, but it planned to expand the service into other territories.

Napster said visitors to its site could listen to any of two million listings for free, up to five times each.

Napster, however, did not indicate in a statement if advertisers were already in place to cover the expense of the new service.

Two million unique visitors visit Napster' Web site every month, according to the company.

Shares of Napster (Research) climbed seven percent in Friday trading on the Nasdaq stock exchange.
