But legally speaking, this is indeed infringement. These music can only be used for personal appreciation, and playing Olympic songs as a shop is suspected of attracting customers and making profits. China has promulgated the Regulations on the Administration of Special Signs and the Regulations on the Protection of Olympic Signs. According to these laws, this is indeed an infringement. As a legal citizen of People's Republic of China (PRC), you must abide by the law.
Therefore, playing music in shopping malls without the permission of the Olympic Committee is indeed an infringement and should be stopped immediately.
