https://www.youtube.com/channel/UCLXo7UDZvByw2ixzpQCufnAThis lady is deconstructing it and she's like ok they purposely rap like that... yes they do but they don't really use a formula... I don't believe that.
When they rap, they just rap.
And if it comes out like it does, it just comes out like it is. I doubt anyone who is rapping is actively thinking how they are going to rap and following a formula...
The way it comes out is just how the person is vibing to the flow..
Sometimes you gotta stretch the words... speed up the words.. etc etc...
All these "bars" blah blah .. i mean... I doubt it..
Maybe I'm wrong.. but I know when I "rap"... (every hmong guy's a rapper nowadays right?)... You just find a beat, ride it, and manipulate the words how you have to. Nobody's thinking of a formula.
