Answer 1

It’s not RNB. It’s R&B which stands for rhythm and blues.
It was the name given to black music early in the 20th century to the predominantly black music based in blues, soul, gospel, and other black influenced styles.
Much of it was usurped by white musicians since and spawned such genres as rock and roll, big band, southern rock, and nearly every other popular music genres you can think of.
