Okay, okay, perhaps I shouldn't give up the day job. Misogyny and ostentatiousness isn't my thang, but I do enjoy a twerk or two.
Whether you're a fan of 2015's album of the year To Pimp A Butterfly by multi-Grammy award winning Kendrick Lamar or mocked Kanye's pleas to Mark Zuckerburg to fund his ideas (he needs it, he believes the battle of 300 was the Romans and they were somehow in combat with the Trojans - so cash for access to Google would be welcomed) you can't deny a rapper's artistry with words.
Not your Jay Zs - if I do say so myself, if I do say so myself - I'm talking proper rappers, who think on their feet during battles with razor sharp wit and poetic speed. You need to be proficient with prose and vocabulary.
Professional copywriters are now seeing rap as a legitimate way to write in its own right (check the homonym) as it helps with word formations, storytelling, testing and discipline.
