According to ALEXA statistics, Baidu's MP3 search traffic is enormous, becoming the second largest search after regular web searches, accounting for 16% of its traffic. Therefore, it's not hard to understand that Baidu would rather go to court with domestic record companies than abandon this copyright-infringing search.
However, Baidu is not shameless to the point of being reckless; it does have some concerns, mainly fearing accusations from foreign record companies. Since Baidu is listed in the U.S. and more than 51% of its capital is American, Baidu knows what consequences such legal disputes could bring. Therefore, Baidu cleverly employed a trick on its MP3 search, ensuring that only Chinese users can normally use Baidu's MP3 search.
