Abstract:In China, digital music market is growing rapidly and is huge, the dilemma faced by copyright management of digital music can not be ignored. Copyright management of digital music covers three links: confirmation of copyright, use of copyright and protection of copyright. They face difficulties in determining the ownership of copyright, barriers to cross-border licensing and royalty payment, and imperfect technical and legal protection, respectively. Blockchain has the characteristics of multilateral cooperation, non tampering, traceability and decentralization. If it can be applied, it will solve the dilemma of copyright management of digital music. At the same time, in the three major links of confirmation, use and protection of copyright, they face new problems such as the verification of false claims of copyright, the reduction of actual revenue, and the undetermined nature of evidence of blockchain deposition , respectively. Based on the analysis of the scenarios and challenges of the application of blockchain in copyright management of digital music, the article proposes that China should adopt the "regulatory sandbox" for experimental regulation.
