I doubt he's a psyop. It's polished for a rap video, but it's nothing creative or trend setting. Nevermind that production usually goes up when you grow in popularity.

There are tons of rappers (even nowadays) that are simply more musically creative. His rhyme schemes are incredibly repetitive and rarely change from song to song. It's always the same shit, with little to no variation. He's white, angry at current affairs, he was homeless, drugged out, yada yada MM 2.0. I'm less into rap now than I was a while ago. But the dude gives me vibes of caution. On top of thinking his music is just bland.
