It is the record label that transformed Diamond Platnumz into Africa’s biggest musical export, but for rising Bongo sensation Moses Luca, the WCB empire is a “minefield” he had no intention of crossing.
Luca, who was crowned the winner of Bongo Star Search (BSS) in 2025, has sent shockwaves through the Tanzanian music industry by confirming he rejected a contract offer from Diamond Platnumz’s Wasafi Classic Baby (WCB).
In a candid appearance on the B4TheFame podcast, the Congolese-born singer revealed that his decision was heavily influenced by the well-documented—and devastating—legal wars fought by previous stars who tried to escape the label.
Luca’s refusal to sign stems from the industry-wide phenomenon dubbed the “Harmonize Curse.”
In 2019, superstar Harmonize—WCB’s first major success story—sent the Tanzanian music world into a tailspin when he attempted to terminate his 15-year contract.
What followed was a vicious, multi-million shilling legal battle that saw the ‘Kwangwaru’ singer forced to sell off assets, including houses, to pay a staggering Tsh500 million (Ksh24.8 million) exit fee just to regain the rights to his own name and music masters.
For Luca, the “Harmonize Curse” was a warning sign that the price of Wasafi’s massive marketing machine was simply too high.
“Nisingeweza kusaini mkataba wa miaka kumi ambao unanibana kila kitu,” Luca said, referencing the rigid nature of WCB agreements. (I couldn’t sign a ten-year contract that restricts everything I do.)
He continued: “Nilijifunza kutokana na yaliyowatokea wengine. Sikutaka kufika mahali ambapo nitahitaji kuuza vitu vyangu ili nilipe deni la kununua uhuru wangu mwenyewe.” (I learned from what happened to others. I didn’t want to reach a point where I’d have to sell my things just to pay off a debt to buy my own freedom.)
The controversy surrounding WCB’s contracts is no secret.
Former signees, including Rayvanny and Rich Mavoko, have all parted ways with Diamond’s label amidst claims of “oppressive” management, high revenue-sharing percentages, and a lack of creative independence.
Insiders suggest that WCB contracts often claim a massive cut of an artist’s total earnings, leaving very little for the performer once the label’s overheads are deducted.
For Luca, the allure of Wasafi’s fame wasn’t worth the risk of losing ownership of his future.
“Mimi naangalia legacy, siangalii tu hela ya haraka haraka,” Luca told the podcast. (I am looking at legacy; I’m not just looking for quick money.) “Wasafi ni wakubwa, lakini mimi nataka kuanza njia yangu mwenyewe bila minyororo ya mkataba mrefu.” (Wasafi is big, but I want to start my own path without the chains of a long-term contract.)
By choosing to remain independent, Luca is taking a gamble that very few Bongo Flava artists have attempted since the rise of the WCB juggernaut. He is betting that his raw talent—and a clean legal slate—will be enough to keep him at the top of the charts.
Diamond Platnumz, who famously congratulated Luca during his BSS win, has not publicly commented on the rejection. However, the singer emphasized that there is no “beef” between him and his mentor.
“Diamond ni kaka yangu na nanamheshimu sana kwa kile amefanya kwenye gemu, lakini kwenye biashara tulitofautiana kidogo,” Luca concluded. (Diamond is my brother and I respect him a lot for what he has done in the game, but on the business side, we differed a bit.)
Whether Moses Luca’s gamble will pay off—or whether he will eventually face the same pressure to seek a major label partner—remains to be seen. For now, he is the rare star who has decided to keep his crown, and his contract, firmly in his own hands.
