Background and Release In October 2024, Lali gave an interview to Agustín Gómez Cascales for Shangay, during which she discussed, among other topics, the production process of "Fanático" and her upcoming sixth studio album.

On Monday, 25 November 2024, Lali took to the streets of Buenos Aires to promote the upcoming single, riding through the city on convertible car with a megaphone.

[2] Candela Mazzone of Infobae noted that the song evokes the essence of Argentine rock, drawing comparisons to bands like Babasónicos and Intoxicados.

[10] Julián Otal Landi from Agencia Paco Uriondo commended Lali's decision to move away from the current trend of urban artists revisiting rock in a nostalgic but passionless way.

[1] In the article "Opposing Views" in La Voz del Interior, two music critics expressed contrasting opinions on "No Me Importa".

In contrast, Noelia Maldonado criticized the lack of coherence in Lali's musical output, labeling the single as "a mediocre song", with a sound that evokes artists like Pink or Avril Lavigne, offering little in terms of innovation.

In the same shot, she is seen passing by other iconic landmarks and areas such as the Obelisco, Puerto Madero, and La Boca, all from the back of the convertible, singing into a megaphone.

[16] In the next scene, Lali steps onto an outdoor stage set up on the street to perform the song, backed by an all-female band, in front of an enthusiastic crowd waving flags, jumping, and even moshing.
