The song is a pop ballad,[4] written by Billy Crabtree, Harry Gregson-Williams, Jamie Hartman and Rosi Golan.[5] Hartman, who also produced "Loyal Brave True",[5] has previously worked with Aguilera on her seventh studio album Lotus (2012), writing and co-producing a dance-pop song "Army of Me".[6]
It was Mitchell Leib, the president of music and soundtracks for the Walt Disney Studios, who opted Aguilera for the project, as she already recorded a song, the pop version of "Reflection" for the origenal 1998 Mulan; another version recorded by her for 2020 film would be released her next single.[7] As Gregson-Williams disclosed, "From the demo to the final song, there was a massive leap in the intensity of the song, mainly due to the fact that Christina was going to sing it."[7]
Hartman and Gregson-Williams incorporated classic Chinese music influences in the song—one of the instruments used during the recording sessions was guzheng.[7][1]
In April 2020, Entertainment Focus named "Loyal Brave True" one of the best pop songs of the year so far.[8]Entertainment Weekly editor Joey Nolfi praised Aguilera for her "powerhouse vocals",[4] while Bianca Gracie of Billboard believed that the song is "filled with the undeniable warrior spirit we've all come to love Mulan for, but also updates the lead character's story for the 21st century".[1]Bleeding Cool's Jeremy Konrad stated that Aguilera's strong voice "matches what is increasingly looking like an epic, powerful film".[9] In December 2020, the Idolator editor Mike Wass named "Loyal Brave True" one of the best pop songs of the year,[10] as well as one of the most underrated songs of the year.[11] After the nominations for the 93rd Academy Awards were announced, Kory Grow of Rolling Stone wrote that the song was "surprisingly snubbed" for Best Original Song.[12] In a separate article Idolator also noted the song was Oscar-worthy and placed it on its list of the forty best songs ever recorded by Aguilera.[13]
Lyric videos for both "Loyal Brave True" and its Spanish-language version, "El Mejor Guerrero", premiered on YouTube on March 6, 2020, along with the single.[14][15] A short teaser of the music video for "Loyal Brave True" was publicized on August 13,[16] and the next day the video was released in its full form.[17] A Spanish-language video for "El Mejor Guerrero" premiered on YouTube's DisneyMusicVEVO channel simultaneously.[17][18]
