People take music too seriously. Its not always about saying something super deep.
Rap as a genre has the most inner haters. If they don't relate to the song or its not they're preference it "sucks."
On that note... HYPE BEASTS WE KNOW BOUTCHA, DONT BUY SHOES UNLESS DEY POPLAH
You've obviously never met a metalhead, or a scene kid, or etc.
Plus, it's not about "always saying something super deep," it's more about "not sounding like you just learned how to rhyme two words together five minutes ago on a beat that sounds like somebody went and bought a Casio keyboard on a whim, without knowing how to play."
