Kendrick Lamar has been widely liked in his music ratings. From RateYourMusic, the top albums of the last 10 decade, Lamar dominates the chart with Pimp a Butterfly at no. 1 and good kid +m.a.a.d city at no. 3. It's clear that people value his music higher than other rappers' albums (as they are likely not as consistent). The messages and the themes are also very consistent and empathize well with people, as he rallies black men and those livin' in the hood. Even just extracting a random verse,
"N----, and we hate po-po / Wanna kill us dead in the street fo sho' / N----, I'm at the preacher's door / My knees gettin' weak, and my gun might blow / But we gon' be alright,"
"The yam is the power that be (that be, that be, that be, that be, that be)
You can smell it when I'm walkin' down the street
(Oh yes, we can, oh yes, we can)
I can dig rappin'
But a rapper with a ghost writer?
What the fuck happened? (Oh no)
I swore I wouldn't tell (tell, tell, tell, tell)
But most of y'all sharing bars
Like you got the bottom bunk in a two-man cell (a two-man cell)
Something's in the water (something's in the water)
And if I gotta brown-nose for some gold
Then I'd rather be a bum than a motherfuckin' baller (oh yeah)",
"I'm the biggest hypocrite of 2015
Once I finish this, witnesses will convey just what I mean
Been feeling this way since I was sixteen, came to my senses
You never liked us anyway, fuck your friendship, I meant it
I'm African-American, I'm African
I'm black as the moon, heritage of a small village
Pardon my residence
Came from the bottom of mankind
My hair is nappy, my dick is big, my nose is round and wide
You hate me don't you?
You hate my people, your plan is to terminate my culture
You're fuckin' evil I want you to recognize that I'm a proud monkey
You vandalize my perception but can't take style from me
And this is more than confession
I mean I might press the button just so you know my discretion
I'm caught in my feelings, I know that you feel it
You sabotage my community, makin' a killin'
You made me a killer, emancipation of a real nigga"....
My opponent might consider Eminem, considering I myself conceded he might be a better rapper in terms of flow and delivery, but Eminem has a lot of copy cats and the majority of his career was sparked by Lose Yourself in the decade of 2000's. With Lamar's rise in action, I can't help but think that he is the best rapper of the last decade (even if I personally dislike his music).
