long story short werra was against blaise and tata adding songs,just them 4 the co leaders and blaise was upset with it jb in order to try to appease things said he'd sacrifice his song for blaise and blaise said no it does not make sense,then after a lot of arguments they got the 6 guys to have a song,which then lead to upset from the rest from the main guys like titina mpela aimelia to the rest and blaise was saying if he does not get his song he wont participate to the project
i think in reality issues in the project started from manda chante getting into the " pentagone" project,then reluctance to include ferre while late seguin was included effortlessly in a similar position on which most of the big 4 did not have a particular issue with but they had to be diplomatic in support of those who had an issue with it,like they used to do back when the group was united
