Waka made rappers focus on how something is said, rather than what's being said. the phrasing over booming production. Waka himself was the logical next step from Lil' John. Migos took that template and perfected it by making it more melodic within that Flow everyone started biting
their sound and flow is possible because Lil' B opened the flood gates on what's possible on record because he said let me be silly and ridiculous over BOOMING production
many wannabee and emerging rappers looked at B and said if can, so can I. and also said he on that silly shit, let me make street shit, but use his template
Migos feel like Lil B (non-boombap Lil B) and Waka merged into one thing
