Song on the 1977 Richard Hell and the Voidoids album of the same name.

I belong to the blank generation
And I can take it or leave it each time
Well, I belong to the...generation
But I can take it or leave it each time

(music and lyrics by Richard Hell)

According to Hell:

People misread what I meant by 'Blank Generation.' To me, 'blank' is a line where you can fill in anything. It's positive. It's the idea that you have the option of making yourself anything you want, filling in the blank. And that's something that provides a uniquely powerful sense to this generation. It's saying, 'I entirely reject your standards for judging my behavior.' And I support that entirely."

(The ellipses in the third line of each chorus is an actual vocal pause, representing that blank for the listener to fill in)
