The first recorded rap song (1926) was a country song, by a White musician, Chris Bouchillon, but the lyrics suggest his source was Black. https://youtu.be/aPrnbGm7jas?si=dtQkpm2D0lcJxPXs

Most early country music by Black musicians during the hillbilly era never got recorded or written about. One exception is the 11 songs by Andrew and Jim Baxter. I'm working on an article about them.
