Does Bollywood Glorify Sonu , Udit , Kumar , Alka If They Passes Away

I mean will they glorify them as great as rafi , mukesh , kishore  era  after they are physically dead i mean no one care about alive talent but when they passes away people started claiming ooo what legend he/she was , oo he was so great ...  similar instances where Muhammad Rafi was sidelined by music directors they tried to create another rafi but failed at that point limited singers used to sing for bollywood films as there was no autotuner thing for pitch correction at that point , or besides him kishore kumar the most controversial singer of his time or even mangeshkar sisters
