I haven't watched much and only heard some western and K-pop songs. Is there a copyright issue?
Earlier this year, I watched an international volleyball tournament, VNL. The event organizing body said they would play songs of the nations of teams competing in each match. They played J-pop songs when Japanese teams played for 2-3 days and, later, played K-pop songs instead (showing ignorance thinking K-pop and J-pop were interchangeable).
