koffi  is kind of using the technique he used with fally by telling on tv what should have remained secret to put pressure on fally to come and participate to album, he has said on various tvs that ferre has refused to participate to clip of their feat while always insisting that its ferre himself who wanted that feat and came to studio
on the other side,from what i hear ferre's staff convinced him not to go to clip or koffi might "steal" all his success as they think doing that feat with koffi already made him go down a bit while koffi  kinda went up and that koffi despite saying on tv that he respects ferre's decision,is very angry and insults ferre in private

I predicted this quite strange

Ferre aza zoba....
pfff Koffi stealing his succes. It is/was his own fault that his fame is/was descending, by releasing 3 garbage generiques, while people were waiting for generiques who would be more powerfull than Boite Noire and releasing a long awaited diss-song which sounds almost the same like one of his Boite Noire songs. pfff and then unnecessary searching for polemic and blaming Koffi for stealing his succes......

lol koffi said in one of his interviews that fally was the undoubtable number 1 of the new generation whereas in the past he was just praising them both a bit(even praised ferre much more often than fally),maybe that also hurt ferre 

Ferre should've just done the clip. And Mvulusi, Vieux Jaloux sounds nothing like his Boite Noire songs, it soubda like something from Sens Interdit or QEDT.

Ferre is just badly advised by the waste people he surrounds himself with

Ferre's just a fool

I don't believe the featuring can cause damage to any of them rather than complement whatever success they have so far .
