Way too heavy on the "it's so hard to be a black kid that likes white music," thing.
Dude that's why it's so damn funny. He's NOT being serious at all. You have to understand that he is A COMEDIAN first and THEN a rapper. Most of what he says is sarcastic and overdone for comedic purposes. I see him as a sort of "Black Eminem", Not talent-wise or even content-wise, but I mean in the style: The way that he says the most outlandish shit and never means any of it. Obviously Gambino is a little softer and more "backpack" than Eminem, and I LIKE THAT... because he's being himself. He doesn't pretend to be a gangster or any of that bullshit.
I also love the instrumentals, they sound beast as fuck in my car.
I recently just got into Gambino (my girlfriend started playing it in the car and that's how I discovered it.... She has also introduced me to John Mayer's music, but that's a story for another day) so yeah, I haven't heard "Royalty" yet, but I'll check it out.
