L'Amour de Ma Vie

Following her second studio album, Happier Than Ever (2021), Eilish continued collaborating with her brother Finneas O'Connell, and the following year she surprise-released Guitar Songs (2022), consisting of two tracks. In October 2022, she revealed in a Vanity Fair interview that she had also made another track, before experiencing writer's block, which was broken by her involvement in the soundtrack of the 2023 film Barbie, for which Eilish contributed "What Was I Made For?"—which became her second number-one single in the United Kingdom and earned her a second Academy Award for Best Original Song, after "No Time to Die" (2020).^[1]

In an interview with Apple Music's Zane Lowe, the siblings recalled that they made a song called "Over Now" in October 2022 with the purpose of being a track to exercise to. For over a year, they did not decide what to do with the song, with Finneas suggesting releasing it as it was as the "bravest" move. However, they chose to rewrite and shorten it and add it to the end of an unrelated song as a "little surprise". It featured on "L'Amour de Ma Vie", a song with a "mean" and "dismissive" chorus and bridge. The producer said that they wrote verses to justify the negativity present in the rest of the song, which he compared to the previous album track "The Greatest", noting that it contrasts its lyrics.^[2]

Eilish announced the release of her third studio album, Hit Me Hard and Soft, on April 8, 2024, with a promotional video.^[1] Five days later, she previewed "L'Amour de Ma Vie" during her surprise DJ set at Coachella 2024, alongside "Lunch" and "Chihiro".^[3] On April 18, she unveiled the album's track listing.^[4] Hit Me Hard and Soft was released on May 17 as scheduled, with "L'Amour de Ma Vie" as the seventh track on the record.^[5] The following Tuesday, Eilish released the "club-ready" extended edit of the song's second part, "Over Now".^[6] "L'Amour de Ma Vie" debuted at number 22 on the US Billboard Hot 100, landing in the top 40 along with all of the album's tracks, doubling her top-40 entries from ten to 20.^[7]

"L'Amour de Ma Vie" is a two-part song: "L'Amour de Ma Vie" and "Over Now".^[2] It is about the dissolution of a relationship, starting as a retro and bossa nova-influenced side, before segueing into an electronic part.^[8][9] Media outlets noted that the track begins as a piece reminiscent of works by late French singer Édith Piaf and Icelandic singer-songwriter Laufey,^[10][11] while the ending has been compared to Charli XCX's hyperpop material, as well as to the Weeknd's "Blinding Lights" (2019).^[12][13] Eilish's attitude on the song was compared to her previous songs such as "Bitches Broken Hearts" and "Party Favor" (both 2018),^[14] while the sonicscape called back reviewers to "Happier Than Ever" (2021).^[15][16][17]

"L'Amour de Ma Vie" has been described as a "lounge", "swingy", and "torchy" ballad,^[18][19][20] combining easy listening, jazz, retro-pop and soft rock genres.^{[9][16][21][19]} Eilish sings in "smokey" and "unrepentant" tone,^[20] reminiscent of Laufey.^[13] as well as Eilish's records such as her debut album and Happier Than Ever's "Billie Bossa Nova".^[11][8] In the first verse, she unveils that she told her ex-partner that she told them a lie–that they were the titular love of her life.^[22] Later, she admits that the situation became ironic, hence they found a new lover, even though they stated they would not be able to "fall in love again because of [Eilish]".^[23] Through this part, she is supported by a "wobbl[y]" and "warp[y]" guitar.^[24] The lyric "And you moved on" starts to be repeated, while the sonicscape changes to an electronic part, introducing club beats.^[9]

The second part,^[a] titled "Over Now", is a high-tempo and "hectic"^[16] disco,^[10] electropop,^[21] hyperpop,^[12][17] and synth-pop^[13] song with synths reminiscent of the 1980s^[13] and Auto Tuned vocals. In particular, a bar of music appears to sample "Children" by Robert Miles, a mid-1990s instrumental single.^[20][26] "Over Now" also incorporates sounds reminiscent of '80s video game noises in its production, to earn a bitpop beat.^[27] During this side, Eilish sings about the outcome of the breakup, as she lays with a woman telling her about her past lover–calling them "mediocre" and addressing that both of them are "glad" that the relationship ended.^[17][28] The part was described as "dark", "pinwheeling[ing]", and "pulsating".^[21][29] In an extended edit, Eilish swoops more biting words towards her previous lover, finishing the song singing: "I wasn't satiated / You're looking older lately / Dating another baby".^[17]
