More proof that there is a market for music subscriptions-according to an article appearing in the Mac Observer, "Napster's subscriber service soared 53% during the company's fourth fiscal quarter. Napster announced Tuesday that its subscriber base grew to 410,000, up some 143,000 users. The company also raised its fourth quarter revenue estimate to between US$16.5 million and $17.5 million, though it did not release earnings estimates.
