When accessing NetEase Cloud Music from overseas, many songs appear grayed out and cannot be played, and QQ Music displays a message saying "Due to copyright protection, this service is temporarily unavailable in your region." This is because music copyrights are licensed separately by region, and the platforms determine your geographical location by detecting your network IP address and block tracks without overseas authorization. (The rest of the text appears to be unrelated and refers to a separate issue within the app.)
