Kendrick is literally the most critically acclaimed rapper ever, and combine this with a huge commercial success, that's unheard of.
in 2024 alone, NLU is the first diss track to go #1, and even when you put that aside, he literally had the entire top 5 of the billboard hot 100 on lock few months ago. That's a feat only The Beatles, Taylor Swift and Drake have done.
Within the same year he had:
-A critically acclaimed album
-The first rap song to win 5 grammy awards since lauryn Hill.
-The second rapper to ever win Song Of the Year and Record Of the Year
-3 number 1 hits (could have had 5)
-Super Bowl slot
-First diss track to go #1
-entire top 5 of the billboard hot 100 on lock
-won a big rap battle
-has many publications ranking his diss track the best diss record ever
-first rapper to headline a stadium tour
... (the list goes on)
And broke many streaming records.
This is the most impressive year for a rapper. No other rapper has been able to reach that level of acclaim combined to that level of commercial success.
