New regulations issues by the Chinese government have outlawed any links posted on search engines that provide access to unauthorized music files. They require all sites offering foreign music to offer the songs they provide to censors. It is estimated that up to 80% of the traffic from Baidu, the most popular search engine in China, comes from searches relating to unauthorized music files. All digital music services will be forced to provide written lyrics, in Chinese, for each and every song they offer and prove they have a legal right to distribute them.
