Here's a freedom song from Aretha:

This song seems appropriate

My first thought, Freedom, Richie Havens at Woodstock

Jon Batiste

"Freedom Blues"

I hope that I should live to see,
When every man can know he's free.
Sufferin' from the past.
I make I ought to be sad

I got my duty rock and roll,
Now everybody, everybody, everyone's gotta be free!
Oh...

Now la-la, la-da-da-da.
La-la, la-da da-da.

Mmmm, let's get rid of that old man, hey-ey-ey,
And bring our government up to date.
It may be very hard to do,
Just open your mind, let love come through.

You hear me callin' you my?
Everybody, everybody, everyone's gotta be free!
Oh yes!

La-la, la-da-da-da.
La-la, la-da da-da.

We did our thing every thing and we paid our dues,
Now let's get rid of these freedom blues.
It may be very hard to do,
Just open your mind, let love come through.

I got my duty rock and roll,
Now everybody, everybody, everyone's gotta be free!
Oh...

La-la, la-da-da-da.
La-la, la-da da-da.
La-la, la-da-da-da.
La-la, la-da da-da.

first song that came to my mind. Free, if not connected muchly with Juneteenth

Donny Hathaway, Someday We'll All Be Free

Lift Every Voice and Sing

This may not have the word 'free' in the title, but I do recall, in the documentary 'Eyes On The Prize', a woman from the civil rights movement of the 60s saying how they loved this song at that time and how it lifted her spirits.

And here's Nina Simone's classic, 'I Wish I Knew How It would Feel To Be Free'

Freedom Riders
