Napster, the reformed music exchange service, has picked up another major distribution channel for its new prepaid music card. Six weeks ago, Napster launched the card, which offers 15 downloads for 99 cents each, and projected it would have the cards in 20,000 retail locations by year’s end. This week, RadioShack, and its 7,000 outlets nationwide, signed up to offer the “Napster Music Card.” At its launch in late October, Roxio had signed up Best Buy, CompUSA, Kroger, Safeway, RiteAid, ExxonMobil, Duane Reade, Diamond Shamrock and Speedway/SuperAmerica as distributors. The new card offers 15 downloads for $14.85. A scratch-off surface conceals a PIN that recipients use to activate the credits for permanent downloads from the Napster service. The Company also announced this week it is offering a free trial of its premium service, and has launched the “Napster Burnpak” which allows music fans to produce their own CDs, complete with custom labels, and add music to their photos and videos. Napster offers access to the largest catalog of online music with more than 500,000 tracks spanning all genres and artists. For more information visit http://www.napster.com.
