Ever heard the song Nappy Heads by The Fugees? Sure doesn’t sound like a respectful reference he’s making there to me. Mocking the shit out of him with his impression, and then he says, “But what the fuck was so wonderful 'bout pickin cotton, on a farm?”

Bob O’Meally, the head of jazz studies at Columbia University in New York, remains divided. While lauding Armstrong as “one of the greatest people of the 20th century”, he was “offended by his presentations … At the time of the rise of Malcolm X, the authority of Martin Luther King, examples in the popular media like Muhammad Ali and others, there was Armstrong – a kind of throwback from another era, with this borderline minstrelsy role that he played. I cringed as a black American.”

“Armstrong was regularly called an Uncle Tom.”

Armstrong’s hesitancy to speak out against racism was a frequent bone of contention with his fellow black entertainers, some of whom branded him an “Uncle Tom.”

“During the civil rights movement and beyond, many Black Americans viewed Armstrong as a subservient Uncle Tom figure, a perception "Black & Blues" refutes.”

I love the song. The context is that OP is nominating it to be ‘humankind’s anthem’ ffs, so it definitely seems relevant to bring up controversy. I pointed out there would be push back, and generally topics like this become a much bigger deal for much lesser titles.
