This is very true. His albums have ranged from CAC friendly (College Dropout, Graduation) to outright CAC pandering (LR with Jon Brion, Yeezus)
Say sampling curtis mayfield and marvin gaye is "Cac friendly" brehs.
His whole steeze on College Dropout, Late Registration, even Graduation is paying respects
to musicians he respects a great deal from Ray Charles to Michael Jackson to Marvin Gaye.
If anything his earlier music is a direct call back to 1960's/1970's/1980's Black America but this changed with 808's and Heartbreak and the album that came after that.
He (or someone on his team
) started sampling from rock, using production styles
from EDM etc. and added it into his Hip Hop. The soul and jazz samples left, the orchestra left, the bounce and swing he was known for started disappear in favor of something else.
This coincides with about the time his ego started to run out of control and he was looking for a private pornstar to marry (Amber Rose, Kim K etc.)
