Known for her distinctive overall use of Auto-Tune, Bad Gyal has developed a strong cult following ever since her musical career began in 2016, with an interpretation of Rihanna's "Work" in the Catalan language.

Bad Gyal later released two mixtapes: Slow Wine (2016) and Worldwide Angel (2018), which established her as an emerging artist within the Spanish urban scene.

[7][8] After "Pai" gained popularity on YouTube, and was picked up by a local radio, Farelo started recording Slow Wine Mixtape, alongside producer Pablo Martínez.

The mixtape was released on 9 November 2016 and caught the attention of several professional magazines and music outlets, including Pitchfork and Fact.

She also released "Open the Door" featuring Jamaican singer Govana, "Yo sigo iual" and "Unknown Feeling".

In October 2019, Farelo collaborated with Omar Montes on "Alocao", which peaked at number one in Spain for several weeks and is certified five times platinum.

[26] On 25 June, she collaborated with Mariah Angeliq and María Becerra on "BOBO", which sampled TLC's "No Scrubs" and sparked controversy due to similarity with Luchy DR's "Bufón".

[27][28] As tour season came to an end, Farelo published "Flow 2000" as well as her second extended play Sound System: The Final Releases featuring songs she had been performing live for years yet remained unreleased.

[29] She released "A la mía" in parallel, exclusively for the Grand Theft Auto Online radio station Motomami Los Santos hosted by Rosalía and Arca.
