Think about what was valuable in slaves. Physical Prowess (Stronger slaves means more work can be completed in the fields), and talent (slaves that can keep other slaves entertained mean they're not planning a revolt).
Keeping the slave master entertained by singing and dancing also brought perks for the slaves that are able to do so. Being able to produce more value in the field also brought perks.
Now think about the industries Black Americans dominate today... Athletics and Entertainment.
