Napster (NSDQ: NAPS) Japan has added music videos to its unlimited over-the-air subscription service, Napster To Go. The new service is dubbed Napster Clips, and is only available on the N906iL onefone handset on DoCoMo (NYSE: DCM). This is Napster’s first video service and operates over DoCoMo’s 3G network or its Home U LAN service. DoCoMo and Napster Japan will be rolling out a co-marketing campaign with the launch of the new video service, which will coincide with the handset launch. Napster has more mobile subscribers than PC subscribers in Japan. Napster is currently the subject of a proxy battle, and AT&T (NYSE: T) announced last week that it would increase the number of its customers who could access Napster.
