.MP3 is the second studio album by Argentine singer-songwriter Emilia, released on 3 November 2023, through Sony Music Latin and WK Records.

It has been supported by seven singles: "Jagger", "No Se Ve" (with Ludmilla), "Guerrero", "GTA", "La Original" (with Tini), "Exclusive" and "Jet Set" (with Nathy Peluso).

[4] Emilia co-wroted it and worked with producers including Big One, Mauricio Rengifo, Andrés Torres, Valyum, and Zecca.

[4] The concept of .MP3 revolves around a revival of the female-driven pop of the 1990s but predominantly the 2000s era, the music that Emilia listened to while growing up.

[5][6] As such, she has mentioned U.S. pop stars such as Beyoncé, Rihanna, Missy Elliot, Gwen Stefani and Pink as some of her biggest inspirations,[6][7] as well as Latin American singers like Shakira, Thalía and Paulina Rubio.

"[6] The album's second track and lead single, "Jagger" has been described as a 2000s-inspired dance-pop[11][12] and urban pop song, with elements of hip hop.

[13] In "La Original", Emilia and Tini sing over a piano house beat about "fully embracing themselves behind the scenes once the cameras turn off".

"[6] Wonderland defined the song as an "immersive and groove-laden track that is designed to get listeners on their feat, rhythmically and stylistically unique".

[6] Over pulsating beats, Emilia sings about a "hot-and-heavy romance that she can't get out of her head",[10] and "giving a private show to the man she likes".

[18] Shortly after her performance at Billboard Mujeres Latinas en la Música, Emilia announced her international 2023 Tour, which began on 14 May in Mexico City as part of the Tecate Emblema festival.

[20] On 9 October 2023, Emilia posted a video in her Instagram account teasing the album's release, which shows her in a bedroom that resembles that of a teenager in the 2000s, with walls full of posters, synthetic hair rugs and other typical objects of the time.

[23][24] Following the album's overall concept of 2000s nostalgia, the cover shows a CD case with a picture of the singer leaning on an MP3 player.

[28] On 29 October, Emilia celebrated her birthday at a big party in Puerto Madero, Buenos Aires with the theme of the album and its reference to the 2000s,[30] in addition to revealing on her social media accounts that the tracks "Iconic" and "La Original" would feature Nathy Peluso and Tini, respectively.

[31] The album was released for digital download and streaming on 3 November by Sony Music Latin and WK Records.

[41] In the Argentine Chamber of Phonograms and Videograms Producers (CAPIF)'s Top 10 ranking of the most listened to songs in the country, the single peaked at number 8 in the week of 14 April.

[45] The single's accompanying music video was directed by Ballve[46] and has been noted for its reference to 2000s fashion, with the singer wearing bandanas, large-size earrings and sunglasses, and low-rise jeans.

[62] In line with the overall theme of the album, the video "brings many of the Y2K trends, including neon, lace-up tops, rose-colored sunglasses, and more.

[41] The music video for the song, directed by Rocío Gastaldi, shows the singer traveling in time to her childhood home to accompany her father in his illness, but also herself as a child.

[15] Directed by Ballve,[73] the music video "walking onto a runway while watched by fashion critics before they start singing the lyrics to their catchy track as they sport headpiece mics reminiscent of Britney Spears' best performances.
