"Song of General Kim Il-sung" and "Song of General Kim Jong-il" have since taken the place of de facto national anthems domestically, and "Aegukka" is reserved for representing North Korea internationally: when foreign dignitaries visit the country or North Korean athletes compete at international sporting competitions.[10] Compared to other nations, the North Korean national anthem is not often performed inside the country (except for radio and television sign-off) and thus many North Koreans do not know the lyrics.[10]
