A couple of reasons, Amapiano is the in sound right now so a lot of people listen to it so it caters to that, secondly it got pushed by tiktok which helped, thirdly it was release in summer but pushed during the ghana/Nigeria party season of december when many westerners go and visit there well western black people. These factors all helped it get pushed. It’s a Nigerian singer who has made it in an amapiano sound. That’s massive too because Nigerians push their artists. Congolese don’t push their own artists like Nigerians do as a people. Congolese fans of music the average person of that similar age listens to Fally, koffi, the odd fabregas generique, maybe 1/2 Ferre rumbas and old werra but that’s it and some innos or gaz maybe . There’s not much support to push the genre it starts from within.
