...When a requested track is unavailable, it can substitute audio from several alternative music sources. The proxy can also modify selected request information to address regional availability restrictions. It supports HTTP and HTTPS traffic and can operate as a system proxy or through PAC configuration. Upstream proxy settings and specific NetEase server routing can be configured when required. The project is distributed through npm and Docker for different deployment environments. Because it changes how regional and catalog restrictions are handled, actual availability may depend on music-service policies, licensing, and third-party source changes.
