i notice a lot of rappers nowadays start off good but eventually their skill starts diminishing. Rappers are more often praised for being consistent instead of honing their craft and being better than the last release. Which rappers are gettin better and better with each release?

drake, jigga, ye, ross, and wanye and constantly evolving their flow.

 

[Anti-Anime]
