Menken composed "Love Power" with references to Menzel's signature songs – "Let It Go" from Frozen (2013) and "Defying Gravity" from Wicked (2003) – in mind, and included allusions to the latter at the behest of Schwartz, its songwriter.

American actress and singer Idina Menzel debuted the role of Nancy Tremaine, Robert's (Patrick Dempsey) fiancé, in Disney's musical fantasy film Enchanted in 2007.

[8] Actress Amy Adams, who plays Giselle and also co-produced the sequel, described Menzel's lack of musical performances in Enchanted as the film's "grossest oversight", which they hoped to correct.

[9] Shortly after Disenchanted was announced, Menzel confirmed that she would finally have her own song written by Menken and Schwartz called "Love Power",[9] which she predicted fans would appreciate.

[7][10] Although Menken stated he rarely writes music intended for a specific artist or voice,[11] he had "Let It Go" from Frozen (2013) and "Defying Gravity" from Wicked – both songs famously performed by Menzel – in mind when composing "Love Power".

[29][30] When Giselle's wish for a "fairy tale life" inadvertently turns her into a wicked stepmother, she sends her stepdaughter Morgan (Gabriella Baldacchino) to the animated kingdom of Andalasia to seek help reversing the spell.

[20] Upon reuniting with family friend Nancy, now Andalasia's queen,[31] the character encourages Morgan to harness her most cherished memories of Giselle to restore her stepmother's true nature.

[32] Within the context of the film, "Love Power" serves as Disenchanted's 11th-hour song, described by Taylor as "the big rally cry that elevates the hero's lowest point into the trajectory of their triumph".

[34][35] Micaela Pérez Vitale, a writer for MovieWeb, noticed that the restoration powers of love and memories are also integral to the plot of Frozen II (2019), which also starred Menzel.

[40] The singer belts throughout the track,[38][39] particularly during its chorus,[41] with Taylor describing her final sustained note as "nearly guaranteed to be the longest you'll hear in any tune this year".

[42] According to Shrishty of Collider, the line "Just remember the memories that show us the power of love" ultimately serves as the key to undoing the enchantment that has turned Giselle evil.

[48] Benjamin Lee of The Guardian summarized the song as "a brassy attempt to get a returning Idina Menzel to deliver a Frozen-esque number about the power of love".

[52] Writing for TheWrap, Elizabeth Weitzman said Menzel "knocks [the song] out of the park" vocally,[53] while Ella Kemp of Little White Lies called the track worthy of her career and talent.

[56] Caleb Johnson of the Northern Star called "Love Power" an uplifting highlight, appreciating it for correcting Disney's mistake of not using Menzel's singing voice in Enchanted.

[2] Both Vanity Fair's chief film critic Richard Lawson and Theresa DeLucci of Den of Geek dismissed it as inferior to "Let it Go",[60][61] while the staff of Moviefone said it fails to "move the needle" despite Menzel's impressive performance.

[49] In a negative review, Polygon's Petrana Radulovic accused "Love Power" of wasting Menzel's talent, calling it "incredibly generic and corny".

[20] Laman of Collider ranked "Love Power" the seventh best song from Disenchanted, describing it as lyrically forgettable despite Menzel's performance and criticizing its reference to "Let it Go" as "eye-roll worthy".
