Abstract: Abstract： This paper, after careful consideration of the prosperous development of the digital music market and its strong selfsustaining capability against even largescale infringing activities which are enabled by P2P filesharing networks, concludes that even with limited copyright law enforcement, a competitive digital music market can and will ensure the continuing creation and distribution of music products, while P2P filesharing networks(software), as a neutral technological application, can still stay in the "safe harbor" established in the case of Sony v. Universal.

Key words: "safe harbor", digital music, selfsustaining capability of market, P2P filesharing networks (software)
