if even michael jackson went 10 years almost being called past it and finished before he died,nobody can avoid it,unless death comes "prematurely" to avoid it,even a "kid" in terms of lifelong musical career like arafat went on a very tough year before passing away
absolute glory is not eternal and its a thing both congolese musicians and most of their fans dont like to accept,you can handle things for a while through agressive marketing and constant presence but your peak will remain your peak and will be seen when you are gone if in the heat of the moment the recent times are still seen as your peak
you might have some "cherry on the cake" moments like koffi's u arena when it happens or the 4X4 martyrs ,or messi's world cup but there will always be signs that you are at a certain point of your career,sooner or later
