Well I have the answer for Yuu. Previous national anthem was appropriate because King was the symbol of national Unity. Be it madhesis, pahades, bhaun, newar; King was unifiying factor. Just look at the National anthem of britian and say how it is different than previous nepali national anthem. God save our gracious Queen! Long live our noble Queen! God save the Queen! Send her victorious, Happy and glorious, Long to reign over us, God save the Queen. Thy choicest gifts in store On her be pleased to pour, Long may she reign. May she defend our laws, And give us ever cause, To sing with heart and voice, God save the Queen.
