Music has always been a political tool. Think of all the protest songs of the 1960s. Such as "We Shall Overcome"
Songs such as "Dixie" used in Minstral shows became political when adopted by the Southern States contrasted by "The Battle Hymn of the Republic" or "Marching through Georgia"
But you surprised me with the Internationale:
The Internationale is a left-wing anthem. It has been a standard of the socialist movement since the late nineteenth century. The title arises from the "First International", an alliance of workers which held a congress in 1864. It has become the anthem of communists, socialists, anarchists, democratic socialists, and social democrats.
The German version, Die Internationale, was used by East German anti-Stalinists in 1953 and again during the 1989 protests. In the German version the final line of the chorus reads: "Die Internationale erkämpft das Menschenrecht". The Internationale will win our human rights.
The Internationale in Chinese is the de facto anthem of the Communist Party of China, the national anthem of the Chinese Soviet Republic, and was a rallying song of the students and workers at the Tiananmen Square protests of 1989.
Soon after the October Revolution in Russia it was translated into Russian and became essentially the national anthem until 1944. It is still the official song of the Communist Party of the Soviet Union, and the post-1919 Soviet version is still used by the Communist Party of the Russian Federation.
First two stanzas:
Stand up, ones who are branded by the curse,
All the world's starving and enslaved!
Our outraged minds are boiling,
Ready to lead us into a deadly fight.
We will destroy this world of violence
Down to the foundations, and then
We will build our new world.
He who was nothing will become everything!
Chorus (×2):
This is our final and decisive battle;
With the Internationale humanity will rise up!
No one will grant us deliverance,
Not god, nor tsar, nor hero.
We will win our liberation,
With our very own hands.
To throw down oppression with a skilled hand,
To take back what is ours —
Fire up the furnace and hammer boldly,
while the iron is still hot!
Chorus (×2)
