It's Negara Ku. Meaning "Your Country". Or as the Americans might say "This Land is your Land".
It is a damn moving anthem. Even I as a foreigner can feel their love of country. The Singapore anthem is much
more triumphant. "Majulah Singapura" i.e. "We're gonna win". Good music though.
Majulah S is too boring after a while. Especially if you sing it day in day out at school.
