Napster and Japanese wireless juggernaut DoCoMo have reached a deal that will expand Napster's over-the-air service to cover the entire line of DoCoMo's 904i handsets. DoCoMo, Japan's largest wireless carrier, is Napster's exclusive Japanese partner.

Additionally, the expansion will allow a seamless integration of Napster's PC and mobile-based services for the first time. Consumers will now be able to combine mobile and PC-based subscriptions for one price, and integrate Napster's charges with a wireless bill.

Napster Mobile is available on nine carriers throughout Europe, Asia and North America.
