Between August 2019 and now I made 10 albums/mixtapes. Each album has 22 tracks and none of them sound the same.
Now all I have to do is get them mastered.
It's not difficult to make an album where all of the tracks are different, or they don't all sound the same.
It might be that these MCs/rappers don't make their own beats, so they need to pay producers.
I know Jay Z doesn't make beats. Neither does Nas as far as I know.
But how hard is it to pick 20 beats, make 20 songs, and then delete/cut the 5 worst tracks?
