While not direct Ayn Rand quotes, the band Rush had some "Ayn Rand-ian" type lyrics and messages in their songs
"The Trees" has lyrics that could apply:
"So the maples formed a union
And demanded equal rights
'The oaks are just too greedy
We will make them give us light'
Now there's no more oak oppression
For they passed a noble law
And the trees are all kept equal
By hatchet,
Axe,
And saw"
The song "Anthem" from the 1970's is closer . Read these lyrics and it's clear there's a message especially the parts I bolded:
Know your place in life is where you want to be
Don't let them tell you that you owe it all to me
Keep on looking forward, no use in looking 'round
Hold your head above the ground and they won't bring you down
Anthem of the heart and anthem of the mind
A funeral dirge for eyes gone blind
We marvel after those who sought
New wonders in the world, wonders in the world,
Wonders in the world they wrought
Live for yourself, there's no one else
More worth living for
Begging hands and bleeding hearts will
Only cry out for more
Well, I know they've always told you
Selfishness was wrong
Yet it was for me, not you, I
Came to write this song
"Temples of Syrinx is another:
And the meek shall inherit the earth...
We've taken care of everything
The words you read, the songs you sing
The pictures that give pleasure to your eyes
It's one for all, all for one
We work together, common sons
Never need to wonder how or why
We are the priests
Of the Temples of Syrinx
Our great computers
Fill the hallowed halls
We are the priests
Of the Temples of Syrinx
All the gifts of life
Are held within our walls
Look around this world we made
Equality of stock in trade
Come and join the brotherhood of man
Oh what a nice contented world
Let the banners be unfurled
Hold the red star proudly high in hand
We are the priests
Of the Temples of Syrinx
Our great computers
Fill the hallowed halls
We are the priests
Of the Temples of Syrinx
All the gifts of life
Are held within our walls
