Napster is going to war. The online music service now has a deal with the government to offer a discount to GI's and their families. Music downloads and subscriptions are ten-to-15 percent off, when purchased through the Army and Air Force Exchange Service. Napster normally sells individual song downloads for 99 cents, full albums starting at nine-95 or monthly subscriptions for nine-95. Napster president Brad Duea says the GI's can take the music with them in their Humvees if they want. He says the Napster software makes it easy to burn CD's of downloaded songs. Duea says gift subscriptions are also available for people who want to buy music for the men and women in uniform.
