Not true.
But that's not the sole reason I'm not a fan, there's a lot that doesn't sit right with me about Kendrick, it feels like music coming from a machine to me, possibly calculated by higher ups. Kendrick's shyt feels safe to me, I'm not convinced by him or his music. Just a personal opinion, have 1 or 2 friends that liked his shyt, but I've never felt him despite countless listens. Liked the Compton track though, but he's lacking edge/bite to me.
How is it not true? The record industry didn't start the day Kendrick was signed. Unless you listened exclusively to underground shyt somewhere along the line every major rapper received a push from "the machine", be it endorsement deals, collaborations, or whatever. Going all the way back to RUN DMC and ADIDAS.
And I'm not the biggest Kendrick fan but

Fred.
