Congolese bandleaders of that era were never paying their musicians. Most musicians were also not seeing it as a problem because they were doing it for fun. It only started get a problem when they were really getting fame. The only musician who was paying musicians each month was Koffi Olomide, but it was then only 100 dollar each month which isn't enough if you have a wife and two children at home. Even if he was getting contracts of 30.000 dollars or 20.000 for one concert in an African country like Kenya or Ivory Coast then he was still paying them 100 dollars in a month. It is almost impossible to pay musicians with concerts in Kinshasa if you have more than 30+ with the pressure of fans to live a king (having expensive cars, villa's, sidechicks, etc.) . Because you get only 1000 dollars or 2000 if you are very lucky, but that's is only with VIP-concerts. So if we are talking about those concerts at those little bars, then mawa trop. It's only with concerts in African countries, tours in Europe, mabanga, sponsors like Vodacom, Bracongo, Bralima and matolo to policitians, businessmen, etc., being gigolo, that they survive.
From day 1 its already on the black market and guys screaming from speakers that people can download new albums of Fally, Ferre, Koffi, etc. for 1 dollar and put them on usb-keys. With nobody anything. I witnessed it in 2017, in Matonge when QQJD just came out. Those businesses are mostly runned by Lebanese people, or guys coming from China, Sri Lanka, Pakistan or Nigeria and they are often protected by people from the governement. So they can do what they want. The album sales of Europe were saving bandleaders, but now its even hard to sell for them albums in Europe because of the technology. I don't believe that those problems with Socoda will be solved. If concerts in Europe are allowed again, then they will forgot those stories very quickly.
