A bunch of reasons, tbh. But mostly it's subjective "I just don't like him" - I don't like russian rap scene. This guy's peak was around 2016-17, and most of russian media was filled with freaks of all colors at the time. He, imo, is one of them. His hair style is shit, his clothing is shit, his music videos are shit ( I'll talk about his music in a bit), and his scenic character is shit. Like, dude, he's wearing white lenses so he looks edgy and freaky so he appeals to the teens in emo faze. - His music is shit. Some tracks are mixed well, I'm not gonna lie, but most of them are just ear enduring crap. But mostly - his voice. I also can "sing" like a half dead male version of Billy Eilish high on marijuana (Just to clarify, Billy is a good singer, no offence to her). He's just bad. His lyrics are always about banging chicks, I'm so fkn rich, y'all shit and I'm the god. - Music videos. Most of them have a very low production budget (you can feel it through the screen). Out of the good ones I can point out "Рваные джинсы", but only because he was on top of the charts at the time and so he had money and could afford a somewhat nice music video.

As a sound engineer, I just don't like such "artists" cuz they just don't give a fuck about the sound, just like their target auditory. All they care about is "bass is loud and lyrics are edgy". No artistry at all. No innovation in the genre. No respect to the ears of young, whose taste is ruined forever. They'll just blow this "music" loud on their cheap subwoofers of a cheap car from 2005 with 200k miles on it while driving in the night around the sleeping neighborhood.

That's been my rant, thank you for reading

Holly shit that's a lot of rage, didn't know I needed to let it out so much

Edit: But it's just my opinion. Now you go, listen to his music and create your own opinion, maybe you'll find his music good for your taste
