You're confusing voice and flow. Vocally he sounds similar to Kendrick in a way but flow? Nah. KDot has a more poetic flow which is what makes him unique. J.I.D usually has the calm laid back "I will fuck you up" flow.
When I went to listen to his music and heard NEVER I was like OOOOOOO😱😱😱 That was HIS song. Wowww 😂😂. I love when stuff like XXL actually put you on to new talent.
When it comes to content and delivery that dude will be at the top of this freshman class and aint nan person coming close. Might be hard for people outside the south to pick up on somethings he's saying but that dude is the truth.
First thing first RIP to X and much love and condolences to his loved ones and second, yall gotta check out JID - Never or JID - Hereditary ! Won't disappoint for sure
