What are the Congolese dancing in clubs to? Long rumbas?
? 
Nigerian and other foreigners music except for Innoss it seems the young generation have a real disdain for their culture do not know why
Do you not think that the lack of quality and exposure in rumba right now including generiques is contributing to it?
I think is a combination of factors to be honest. Rhumba despite being this loved genre by donors it is not a genre that gets the public favour like the générique do and on the other hand all the générique are starting to become a very sad and monotopic theme music. In Brazza they all talk about Money and/or sex except for the Two Extras in DR Congo the same. I think that the problem is there aren't any new generations interested in being involved with groups and I understand them. After watching Ado Yuhe, Bon Bon Kojack, JF Ifonge and the many other testimonies about the conditions you have to fulfill to enter groups no youngster in mind with some sane head will go for that. Other then that Leaders are also to blame. Before the War in Congo (the civil ones) they really had money and the opportunities to create a system who could give people jobs and create an elite of sell and adjusted bourgeois people but they didn't, they were all busy fighting and acting childish to have a long term vision and that's why Nigerians had took over they simply had long term vision, plus the style of the Générique us many times this: Fund the most beautiful way to praise the leader if you can understand Lingala the lyrics are "Look at the leader he is so fresh look at him" For example taking a look at Formidable the lyrics are "Ya Ngiama do not care about them since their clothes comes from Sombelanga (Sombela NGA means buying that for me, with this Jamaïque meant that Werra wear the original clothes while the other ask for Europe people or just beg other people to buy clothes for them, which is kinda true since unfortunately a loooot of People in Congo beg for things because they don't have much") or some animation from Genta "Ntsi Ntsi nakobina allez ntzi ntzi nakobina, SUV aleki bangi nakolata... Aleki bango n'a mpembe... Aleki bango na lupemba" Which means I am gonna dance SUV (JB) is way better then them at dressing himself, he is way whiter then them, he has more luck etc " and when I listen to this I am like man why? Do we always have to hear things like these? Leaders encourage that, you will have trouble in a group if you don't have at least one animation where you praise the leader.
With that said, structure, the lack of structure is what really killed Congolese music
