Dont put me in a box and recognize who be the ink king
This is a play on words, dont put me in a box and (but it is said like boxing in order to connect with the last line). With this line astro means dont categorize him as anything, he doesn’t want to be limited with his sound. With “Recognise who be the ink king” he is telling you to recognize that he is the king of writing.
