Another classic example is what happened to Briuce Springsteen's "Born in the USA", taken and used as flag-waving triumphalism by people who never listened to the words:

Born down in a dead man's town
The first kick I took was when I hit the ground
You end up like a dog that's been beat too much
Till you spend half your life just covering up

Born in the U.S.A., I was born in the U.S.A.
I was born in the U.S.A., born in the U.S.A.

Got in a little hometown jam
So they put a rifle in my hand
Sent me off to a foreign land
To go and kill the yellow man

Born in the U.S.A....

Come back home to the refinery
Hiring man said Son if it was up to me
Went down to see my V.A. man
He said Son, don't you understand

I had a brother at Khe Sahn
Fighting off the Viet Cong
They're still there, he's all gone

He had a woman he loved in Saigon
I got a picture of him in her arms now

Down in the shadow of the penitentiary
Out by the gas fires of the refinery
I'm ten years burning down the road
Nowhere to run ain't got nowhere to go

Born in the U.S.A., I was born in the U.S.A.
Born in the U.S.A., I'm a long gone Daddy in the U.S.A.
Born in the U.S.A., Born in the U.S.A.
Born in the U.S.A., I'm a cool rocking Daddy in the U.S.A.
