Disco never really "died". The bandwagon, the fan, the dominance did, but especially among Black folks, it didn't "die" as a backdrop to the music until well into the 1980s. that's how Mike had a monster record in Off The Wall, which had a lot of "disco"-influenced music.

R&B spent many years in a "post-disco" phase, which IMO was like "post-racial"... 'cism still exists, so did disco.

granted, the "Disco Sucks" rally really was more of a symbol of the white divestment in the music more or less. and you know how that goes.

in 1980, the Grammys followed suit as yacht rock was basically scooping up all the awards (the ironic thing about that is some of those records had to conform to the "disco" standard just to get play in clubs).
