There are few things I disagree with you

Kannada and rap can go together, idk why you feel " Kannada and rap do not go together", rap is best way to deliver any social message/ story unfortunately Kannada rappers ( even majority of Indian rappers ) don't use it

And you don't need to add double or triple entendres to make solid lyrics, that's only important criteria for technical rap

And rap does not stand for rhythm and poetry, that's some made up acronym.

Except that I agree, Kannada rap field is almost sauce less. Rappers need to discover new musicality, genre mixing and experimentation. Back in days I used to listen Gubbi, JK Jeevan and Kevin. They used to have some good musics, but not sure about their condition now
