Because the Austrian national anthem is sung very slowly, it completely destroys the singing of it.
That's why I oppose the change that is proposed. I would support the change if it rhymes and doesn't destroy the singing.
Imagine the US anthem is changed from "The bombs bursting in air" to "The bombs bursting in air and over in Iraq, Afghanistan and Libya" - would you still like to sing it ?
Hey we could always change to the fourth verse.
O! thus be it ever, when freemen shall stand
Between their loved home and the war’s desolation.
Blest with vict’ry and peace, may the Heav’n rescued land
Praise the Power that hath made and preserved us a nation!
Then
conquer we must, when our cause it is just,
And this be our motto: “In God is our trust;”
And the star-spangled banner in triumph shall wave
O’er the land of the free and the home of the brave!
