That would depend on what message you want to convey.
James Brown - I'm Black And I'm Proud
Curtis Mayfield - Keep on Pushing
Sam Cooke - A Change Is Gonna Come
P.E. - Can't Truss It
that's just off the top of my head tho.
Black Americans have a unique experience in this country no other immigrant group has including the colonists. No other group in this country was declared by the laws of the land, by the culture of society, buttressed by the pseudo-science of the times to be NOT HUMAN. To be declared no better than beasts of burden on a farm. And that didn't last for a short period of time it lasted for centuries at least 200 years and that's before the end of slavery. That's what chattel slavery intended. And that's NOT like any other groups experience. Even Irish and English indentured servants didn't get that treatment...they were criminals or indebted but weren't declared sub-human. Other immigrants were just kicked out of the country
be it the Chinese (Chinese exclusion act) or Mexicans or even native Americans getting kicked off their own territory as the land was acquired and the country was growing. But their literal humanity and personhood wasn't questioned or denied.
When we sing the National Anthem its a song recounting the struggle against unnamed adversaries and the country's fight for freedom. It talks about surviving thru rockets and bomb attacks and thru out it all we persevered and were victorious. But its understood that song is about fighting tyranny and fighting for independence from other countries trying assert their authority on us even if it doesn't specifically call out Britain or France.
The Black American experience is the same but the big difference is our adversary isn't some foreign country. Its other American citizens who have created laws designed to keep us in bondage and oppression of some sort.
A Black National Anthem has to acknowledge that and that flies in the face of what America is supposed to be. And that makes everyone uncomfortable on both sides. LEV hits all those points and any other song brought up would have to do the same. Its just that LEV strikes a more solemn, somber tone where people today may want something thats not so funeral dirge like..
I would say that other than Native Americans (and I'm sure they do), Black Americans are the only other group in this country who COULD have a national anthem considering all other immigrants voluntarily came here and willfully pledged allegiance to the country as it was and is.
Indians and Blacks didn't have that choice.
