In Nirvana

Walking onto the sidewalk, I heard a young voice come out of the house singing "Don't know what it means, don't know what it means," and it took me a few minutes to place it. It was Nirvana, from 1991'sNevermind:

He's the one who writes
all those pretty songs
And he likes to shoot his gun
And he likes to sing along
And he don't know what it means, don't know what it means

And the singer was Zeke, who is maybe 12 or 13, thus born well after the song was released. Which tells you something about Nirvana.
