Both records reached the top 10 on the Polish charts and spawned the singles "Wasted", "Start a Fire", "Heartbeat", "What You Do", and "Byle jak".

After signing an international record deal with Warner Music in 2016, Margaret released the single "Cool Me Down", gaining particular recognition in Sweden.

Following this genre shift, Margaret returned to radio-friendly pop with her 2024 sixth studio album, Siniaki i cekiny, which yielded the chart-topping single "Tańcz głupia".

Alongside her music career, Margaret has endorsed numerous products, served as a coach on The Voice of Poland in 2019, and starred in the 2022 film Zadra.

[9][3] Shortly after finishing music school, her nasal septum was damaged in a bicycle accident, which temporarily prevented her from playing the instrument.

[7][10] She also began taking private singing lessons from jazz teacher of the Katowice Academy of Music Justyna Motylska,[3] and from vocal coach Elżbieta Zapendowska.

[7][11] At 18, Margaret moved to Warsaw,[12] where she unsuccessfully auditioned for a place at a jazz school, having been rejected due to a droopy eyelid that occurs while she is singing.

[15] In 2006, Margaret appeared on the Polish television talent show Szansa na Sukces ("A Chance for Success"), performing Stenia Kozłowska's song "Będę czekać" ("I'll Be Waiting") and received a special mention.

[16] She returned to the programme in 2009, winning an episode with her performance of Monika Brodka's song "Znam Cię na pamięć" ("I Know You by Heart").

[1] Early in her career, Margaret also recorded soundtracks for Polish television commercials and films, including "Moments" and "It Will Be Lovely Day".

[7] While Margaret was blogging, she was approached by talent agent and her future manager Sławomir Berdowski, who became interested in working with her after hearing her recording of Adele's song "Right as Rain".

[7][26] Berdowski arranged for Margaret to work with music producers Thomas Karlsson, Joakim Buddee, and Ant Whiting, who wrote her debut single "Thank You Very Much".

[98] While working on her third studio album Monkey Business, Margaret voiced Smurfstorm in the Polish-language version of the 2017 animated feature film Smurfs: The Lost Village.

[88][125] Margaret also made a cameo appearance as Gaja Hornby in the 2019 Polish romantic comedy Całe szczęście ("Their Lucky Stars"), and recorded a song of the same name for its soundtrack.

[130] Jarek Szubrycht of Gazeta Wyborcza praised Margaret for her artistic growth, noting that the Polish producers she worked with on the record played a key role in shaping its sound.

[132] The album's title track was released as its first single in April 2019,[133] followed by "Serce Baila" ("Heart Dances") in June, "Chwile bez słów" ("Moments Without Words"; featuring Kacezet) in July, and "Ej chłopaku" ("Hey Boy") in September.

[134][135][136] In July, Margaret collaborated with Polish rapper Young Igi on his single "Układanki" ("Jigsaws"),[137] which was certified two-times platinum in Poland.

[150] At the 2020 MTV Europe Music Awards, she extended her record as the most-awarded artist in the Best Polish Act category, winning for the fourth time.

[155] It was supported by nine singles: "Nowe Plemię";[156] "Przebiśniegi" ("Snowdrops");[157] "Reksiu" with Otsochodzi;[158] "Roadster" with Kizo;[159] "Fotel" ("Armchair");[160] "Xanax";[144] "No Future" with Kukon, released in recognition of the 2020 women's strike protests in Poland;[161] "Antipop" with Kara;[152] and "Sold Out" with Natalia Szroeder.

[163] On 2 July 2021, Margaret released the EP Gelato, which featured two singles: "Tak na oko" and the title track, a collaboration with Polish rapper Tymek.

[195][196] Margaret also recorded a performance for the MTV Unplugged concert special, inspired by Buena Vista Social Club, with guest appearances from Kayah and Otsochodzi.

[217] In January 2024, Margaret released a collaboration with Álvaro Soler titled "Hot Like Summer",[218] followed by the single "Miłego lata" in April, which peaked at number six in the Polish charts.

[231] On the single "Cool Me Down", her vocal range spans approximately one-and-a-half octaves from G4 to C6,[232] and her singing style drew comparisons to Rihanna's, which led to accusations of Margaret copying her.

[127] Having adopted this persona at the beginning of her career to protect her privacy, Margaret decided to reveal it to her fans as a way of sharing a more personal side of her life with them.

[245] Reviewing Add the Blonde, Codzienna Gazeta Muzyczna ("Daily Music Newspaper") described Margaret's voice as distinctive, while Onet noted her versatility, writing that she can sing "seductively, and innocently, and romantically".

[235][246] Onet also commended Margaret for writing her own songs, but Codzienna Gazeta Muzyczna called her lyrics "rather simple and undemanding, emotionally on par with the average listener of the album".

[247] Polish music critic Robert Kozyra took a more negative view of her talent, describing her voice as "small" and arguing that her "weak" live performances reveal her limited vocal capabilities.

[7] Interia and Onet, in their reviews of Monkey Business, criticised Margaret's attempt at singing Polish ballads, saying her "girly" voice is best suited for uptempo songs.

[264] Margaret ranked fifth on Forbes Women Poland's 2022 list of the 100 most valuable female personal brands with an advertising value equivalency (AVE) of 155 million zł.

[288] She also offered to accommodate in her apartment Ukrainian refugees and was among the artists who collectively raised and donated 936,000 zł to the Polish Center for International Aid, which supports those affected by the war.
