Omary Ally Mwanga, known professionally as Marioo (born 31 December 1995), is a Tanzanian singer, songwriter, and music producer. He is also the founder and CEO of his own record label, Bad Nation. He is known for songs such as "Tete", "Dunia", and "Nairobi" (featuring Kenyan artist Bien of Sauti Sol), which recorded high streaming numbers across major digital platforms in Tanzania and Kenya, and was associated with Marioo's increased visibility in the East African music scene.
Life and career
Early life Omary Mwanga was born in Temeke Dar es Salaam to Ndengereko parents from Pwani region of Tanzania. He is the youngest of three children; his late father worked as a public transport conductor (kondakta), and his mother worked at a factory in Vingunguti. While he was still a young child, his parents sent him to live with his grandmother in Kibiti, Rufiji, located in Pwani region.
Marioo attended primary school and began his secondary education in Kibiti, but due to various life challenges, he dropped out during his first year (Form One). Following his departure from school, he returned to Temeke, Dar es Salaam, to live with his mother again. Marioo worked manual jobs to earn a living, including working at a local informal food stall (mama ntilie) and as a motor vehicle mechanic at his uncle's garage before deciding to pursue a career in music.
Early career After an extended period of struggling to establish himself in the music industry, Marioo had his breakthrough in 2016 when his cover of Lameck Ditto's "Moyo Sukuma Damu" caught the attention of producer Emma the Boy. The producer recommended him to the founder of the Tanzania House of Talent (THT) and the late Director of Production at Clouds Media, Ruge Mutahaba, allowing him to successfully join the institution. While training at THT, he networked with already established artists and began composing music for them. Marioo has written numerous hit records for mainstream Tanzanian artists, including "Bado" by Mwasiti, "Wasikudanganye" by Nandy, "Banana" by Dogo Janja, "Mchakamchaka" by Shilole, "Nampa Papa" by Gigy Money, "Pambe" by Christian Bella, and "Nabembea" by Ditto.
The song "Dar Kugumu", which captures the real-life struggles of hustling in Dar es Salaam was Marioo's breakout debut single in 2018. Upon its release, the track was well-received by fans and made him a household name in Tanzania.
Marioo went on to release other successful Bongo Flava singles such as "Raha", "Inatosha", "Asante", "For You", "Anyinya", "Chibonge", and "Ya Uchungu".
In 2020, Marioo released his smash hit "Mama Amina", which was an Amapiano song infused with some elements of Bongo Flava. The song was ranked number 11 on the list of best Tanzanian songs of the decade ranging from 2012 to 2022. His next Amapiano releases such as "Dear Ex", "Beer Tamu" and "Lonely" have marked his status as the king of Swahili Amapiano.
In December 2021, Marioo released "Mi Amor" featuring Jovial from Kenya. The song also became a crossover hit with its visuals becoming the second most watched Tanzanian music video on Youtube in 2022. Rolling Stone magazine ranked Marioo number 39 on its 40 Afropop songs of 2022.
In 2022, Marioo won 3 Tanzania Music Awards from 7 nominations including Best Bongo Flava Song and Best Male Bongo Flava Artist.
Marioo released his debut album The Kid You Know on 9 December 2022. The 17 track album saw Marioo working with different music heavyweights such as Rayvanny, Tyla, Harmonize, and Ali Kiba.
NotJustOk's and Tanzanian music journalist, Charles Maganga praised The Kid You Know by stating that the album has "established Marioo as a mega Bongo Fleva star" and acclaimed Marioo's versatility as "different musical styles such as Amapiano, Afrobeats, and R&B while remaining true to his Bongo Fleva".
In May 2023, Marioo released The deluxe edition of The Kid You Know with three additional singles, "Sing", "Tomorrow", and "Tunamjua".
In Spotify Wrapped 2024, Marioo emerged as the most listened to artist in Tanzania, outranking major regional stars. Additionally, his hit song "Hakuna Matata" claimed the top spot as the most streamed local track of the year across the country.
On 29 May 2026, Marioo released his debut Extended Play (EP) titled MMMCXII, a title derived from Roman numerals representing his date of birth (31 December). The EP marks a transition into a broader "Global African Sound", blending traditional Bongo Flava with Afrobeats, Afro-fusion, Francophone melodies, and 3-step rhythms.
Artistry
Influences Marioo considers Diamond Platnumz his ultimate musical and career role model, though he also deeply respects and draws inspiration from prominent Bongo Flava figures Ali Kiba and Rich Mavoko. He credits Diamond with igniting his passion for music and cites admiration for how he connects with his fanbase and works to help others succeed.
Musical style Marioo's musical style is primarily rooted in Bongo Flava, pop and Afro-R&B, while also incorporating elements of Amapiano and Afropop. Expanding beyond traditional Bongo Flava arrangements, he integrates contemporary R&B beats with Swahili harmonies, a fusion underpinning his romantic ballads such as "Naogopa" and "Mi Amor". He has also been instrumental in popularizing "Bongopiano", a sub-genre that merges South African Amapiano log drums with Tanzania melodic sensibilities, prominently showcased in dance-floor tracks like "Beer Tamu" and "Mama Amina". His recent 2026 output fully demonstrates his stylistic breadth: "Mombasa" channels percussive Bongo Flava; "Pombe", "Sugar 2.0", and "Priority" expand on the melodic Bongopiano and Afro-R&B framework; "Watu" delves into high-tempo Single street-pop while "Doucument" introduces Congolese Afro-Rumba guitar textures. Collectively, these recent releases cement his status as an increasingly versatile and dynamic force in East African contemporary pop.
Personal life Marioo is a Muslim by faith. In 2023, Marioo began dating influencer Paulah Kajala, the daughter of Bongo Movies actress Kajala Masanja and veteran music producer P-Funk Majani.
The couple welcomed their first child, a daughter named Princess Amarah (Amara), on 3 May 2024.
Other ventures
Entrepreneurship In 2019, Marioo established Bad Nation as a multimedia company, which later transitioned into a full record label with the official signing of its first artist, Stans, on 29 August 2024.
Endorsements and partnerships In February 2025, Marioo was officially announced as the national brand ambassador for the National Lottery of Tanzania (Bahati Nasibu ya Taifa), a campaign run by ITHUBA Tanzania aimed at promoting responsible gaming and empowering citizens.
