To go a bit further into detail:
Consequently having nothing but "yes-men" in your corner is one of the worst things that can happen regarding the quality of an artists output. There are many instances where you have really talented artists but they just cant properly turn their talent into full, complete bodies of work. Thats where you need guidance & constructive criticism. Someone telling you "That beat sounds cheap", "You are off beat", "The lyrics need to be rewritten" etc. etc. I had countless moments where I listened to songs where someone delivers a part so horrible it just makes me wonder how the hell not one single person during the recording session or at least during the final mixing stages said anything.
In Ems case he needs someone to tell him point blank that his choppy off beat robot/screaming hybrid flow is like sticking a knife in your ears and its just not enjoayable to listen to. When he was at his peak dude killed his verses and, to me, he always had that anger & power in his voice while rapping. Now he sounds absolutely ridiculous, more like a parody.
One of my fav songs from him is this:
No ridiculous bullshyt, just dope rapping, hook & beat
