I think the main problem with these commercial rappers is they are trying hard to be "Legends" and not being themselves. They see how classic the 90s and early 2000s were, and think they have to spend their whole career living up to it, instead of being themselves. When the 90s rappers first came on the scene, obviously they were competitive, but their main objective was "Imma do me". Now these rappers are like "Imma do like Nas, Tupac, or Jay-Z". Just like J Cole said how legends gotta make room for the new rappers. No nikka, YOU gotta burst on the scene, be original, and take Hip Hop by storm
Everything these new rappers do is so robotic. "Yeah...yeah.. imma say I'm the greatest since Biggie and Pac

"
"Imma sample Outkast and Bob Marley so nikkas would see I'm a legend by association

"
"Yeahh... yeah... imma say, imma murder these nikkas on tracks, and make sure they got no new fans

"
"Yeahh, that'll make me a legend

"
Everything's so robotic now..
