Apologies if I sounded like that.

We're a little off-topic here but I suppose I can see what you mean too. Like black Americans reinterpreting Christian hymns in their gospel music?

I guess I see that as a product of circumstance instead of something innate in black people around the world. And I'm guessing when you say 'black folk music' you're specifically referring to black American music. In which case....you make a good point. Amalgamation, re-interpretation, fusion, deconstruction.

Obviously gets complicated...but do you agree that black American music has a heavy emphasis on creating new things with pre-existing material because they were robbed of their culture/language in the past with the slave trade?

So perhaps there is an innate ability amongst black Americans to do what you're talking about? To build from scratch by amalgamating bits and pieces of one's surroundings into something new.
