Sophia Wanjiku quit her job as a domestic worker in Thika, Kenya at the end of 2020 and made a decision that had no obvious commercial logic: she would record vocals in Kikuyu, a language the industry had long treated as too regional, local, and small, and sell them as sample packs to producers she had never met. This week, the Kenyan singer, performing under her stage name Sofiya Nzau, crossed 750 million total streams on Spotify. No East African artist has done that before

Her path to that number came from an unlikely source. Brazilian DJ Zerb was on Splice, a paid sample licensing platform, searching for a vocal that could anchor a beat he had built. He spent about an hour browsing before he found a Kikuyu vocal clip that matched his instrumental's key exactly. He did not know what the lyrics meant. He reached out to Nzau on Instagram, she told him the song was about a woman fighting for a love her parents refused to accept, and he finished the track. “Mwaki”, which means "fire" in Kikuyu, was released on 10 November 2023. Within weeks, it was viral on TikTok, and within months, it had hit No. 1 on Spotify's Global Viral Chart and spawned remixes from Tiësto, Major Lazer, and Franky Wah. The original track is sung entirely in Kikuyu. Not a word of English.

Following Mwaki's global breakthrough, Nzau became the first East African artist to surpass 10 million monthly listeners on Spotify, held the title of the most-listened-to Kenyan artist on the platform for a significant stretch of 2025, and released “Wacuka” with German producer AVAION, a collaboration that crossed 60 million streams, with Germany emerging as her single largest market.
She participated in Tomorrowland's exclusive Lab of Tomorrow songwriting camp before taking the main stage in Boom, Belgium, becoming the first Kenyan and East African artist to ever perform at the festival, before a crowd of over 400,000. Her European tour kicked off on 13 July 2025 with a sold-out show in Amsterdam, taking her through Berlin, Paris and London. Ahead of the performance, Nzau spoke about what the European tour meant to her, describing it as life-changing and saying the love she felt from fans there in person was something she had not expected at that scale.
PLS&TY's track Your Love (Antdot Remix), which features Nzau, later landed on the official EA Sports FC 26 soundtrack alongside artists including Ed Sheeran.

East Africa has produced world-class female talent for years, talent that has largely been celebrated within the region while the global industry looked elsewhere. Tanzania's Zuchu, a Bongo Flava singer, became the first female East African artist to earn YouTube's Gold Play Button. Kenya's Nikita Kering, an Afropop singer,  swept AFRIMA's Best Female Artist in East Africa award twice. These women did sustained, decorated work. None of them has cracked global streaming numbers at this scale, and that is not a reflection of their talent.

It is a reflection of how slowly the global industry moves on African women, until it cannot ignore the numbers any longer. Sofiya Nzau did not wait for a label co-sign or a feature from a bigger name. She uploaded vocal packs during a pandemic and let the music do what the industry said it could not. The path she has carved is real. The question now is who walks through it next.
