[25][26][27] On 13 December 2019, Mawete released his six-track EP Tsunga Avant L'Album, which was supported by "Game Over", as well as "Zuwa", "Je suis choqué", "Milinga Likolo", "Nako", and "Kibokolo".

[44][45] In an interview with the digital cultural platform Talent2Kin, Mawete disclosed that his musical upbringing was heavily influenced by a variety of Congolese artists, with Werrason being his most significant inspiration.

[44][47][49] Despite their lukewarm commercial reception,[44][47][49] Mawete gained considerable traction with "Etali Nga Te" in 2015 and "Mukolo Ya Zoba" in 2016, tracks that propelled him to prominence in Kinshasa’s music scene.

[54][55][56] He took first place in November 2017 with his standout performance of "Pika", surpassing twelve other finalists, including Voldie Mapenzi, Lionel Ekongo, Jamaica, Christian Muyoli and T2B.

[58] Accompanied by a self-directed music video released in February 2018 under Bomayé Musik by Mukongo Business, the song narrates the story of a boy enamored with his partner, who splurges excessively on her, only to feel betrayed after seeing her with another man, ultimately deciding to overcome the heartbreak and move forward.

"Olingi Nini" gained widespread acclaim across the nation and garnered moderate popularity in other African countries, receiving recognition from fellow Congolese musicians such as Koffi Olomide, Fally Ipupa, Fabregas Le Métis Noir, Celéo Scram, and Héritier Watanabe, as well as from France-based diaspora artists like Youssoupha, Dadju, and Fababy.

[71] Mawete dropped the single "Antidote (Ko Boya Nga Te)" on 8 March 2019, composed by Shedy Beat, with the music video directed by Meddy Saleh and produced under Bomayé Musik by Mukongo Business.

[81] Mawete commenced work on his EP Tsunga Avant L'Album in November 2019 and introduced its lead Congolese rumba-inspired single, "Game Over", that same month through his Instagram page, with the release scheduled for 2 December.

[84][85][86] Within three days of its debut, the EP entered Deezer's top 300 charts on all genres, peaking at 23rd in Russia, 25th in Norway, 32nd in Canada, among other countries,[87] while surpassing one million streams on digital music platforms within a month.

[88] On 19 December, Mawete guest-featured on Dadju's song "Mwasi ya Congo", a tribute to Congolese women affected by sexual violence, with all proceeds allocated to the GiveBackCharity initiative.

[95][96] "C'est Raté" received widespread recognition, garnered over two million views on YouTube within four months,[97] and clinched Video of the Year at the African Muzik Magazine Awards.

[122] Within five months, Puzzle amassed over 10 million streams across digital platforms,[123] peaked atop Boomplay's annual Top Male Songs chart in the DRC, and gained significant traction on TikTok.

[126] He then participated in the Lukin Connexion Lubumbashi-Kinshasa concert on 9 April at the Prestige Lounge Bar in Lubumbashi,[127] followed by a performance at La Maroquinerie in Paris on 5 June as part of Puzzle Tour 1.

[136] Two days later, on 14 July, he joined fellow Congolese singer Singuila on the track "Linga Nga",[137][138] whose video surpassed one million views on YouTube within two weeks and earned over 119K streams on Spotify.
