I know what i want from an Hip Hop album: the best lyricism & the best music.
Kendrick has both of these points imo.
With Kendrick it's really the album in the whole you gotta listen to also, just like Good Kid M.a.a.D City..
This, like GKMC, i just can't explain why it's so perfect.. but Fantano can!
Check this out and hopefully it's come clearer
