yes i agree with the first part because even for example eminem did not even finish high school but he read the dictionary not a rhyme dictionary
but a regular dictionary. and he eventually went back and got his g.e.d.
so it makes sense now when i think about how he is such a great lyricist
with his pronouncation and enuncation with his rhymes and flow.
and as far as rhyming complex and sticking to a topic for a entire verse all the great mc's do it pac did it nas did it etc
u just have to do it in a logical strcuture that makes sense.
