[8] After collaborating with producer and later husband Robert John "Mutt" Lange, she rose to fame with her second studio album, The Woman in Me (1995), which brought her widespread success.

In 2004, after releasing her Greatest Hits album, which produced three singles including "Party for Two", Twain entered a hiatus, revealing years later that diagnoses with Lyme disease and dysphonia led to a severely weakened singing voice.

[37] In the autumn of 1984 her talents were noticed by Toronto DJ Stan Campbell who wrote about her in a Country Music News article: "Eilleen possesses a powerful voice with an impressive range.

[37] Campbell was making an album by Canadian musician (and present-day CKTB radio personality) Tim Denis at the time and she was featured on the backing vocals of the song "Heavy on the Sunshine".

[41] She moved back to Timmins to take care of her younger siblings and took them all to Huntsville, Ontario, where she supported them by earning money performing at the nearby Deerhurst Resort.

[42] Several years later, when Twain's siblings moved out on their own, she assembled a demo tape of her songs and her Huntsville manager set up a showcase for her to present her material to record executives.

[43] In her 2011 autobiography From This Moment On she expressed displeasure with her debut studio album, revealing that she had very little creative control and was frustrated with being unable to showcase her songwriting abilities.

Plus minor country hit "Home Ain't Where His Heart Is (Anymore)" and a re-recorded gospel version of the album track "God Bless the Child" with new lyrics.

[64] After a change in management – QPrime replaced Landau – and a two-year break, along with the birth of their son, Eja (pronounced "Asia") D'Angelo,[65] Twain and Lange returned to the studio.

[79] On June 8, 2011, at a press conference at the Country Music Hall of Fame in Nashville, she announced that she would headline Caesars Palace in Las Vegas for two years.

[82] On March 4, 2015, she announced on Good Morning America she would be going on tour for the first time in eleven years, and would begin June 5 in Seattle, Washington, and end on October 11 in Toronto, Ontario.

[102] On September 23, 2022, Twain signed with Republic Nashville and released "Waking Up Dreaming" as the lead single from her sixth then-upcoming studio album, Queen of Me.

[113] Twain's mainstream pop acceptance was further helped by her appearance in the 1998 first edition of the VH1 Divas concert where she sang alongside Mariah Carey, Celine Dion, Gloria Estefan, Carole King and Aretha Franklin, and also by VH1's 1999 heavily aired Behind the Music, which concentrated on the tragic aspects of her early life as well as her physical attractiveness and Nashville's early resistance to her bare-midriff music videos.

[127] She was guest of honour for a Lip Sync Battle episode on Paramount Network pitting Derek Hough against Nicole Scherzinger that was dedicated to her and her music.

[135][136][137][138][139][140][141] In 1996, Newsweek defended her from detractors who attributed her refusal to tour at the time to her inability to replicate her studio singing live, describing it as "a warm, languid alto sweetened with a wisp of bedroom allure".

[143] Prior to her diagnosis, several physicians with whom she consulted throughout the years primarily attribute the loss of her voice to emotional stress, from which she has since recovered after experimenting with various relaxation techniques and devoting a lot of time to vocal warmups.

[148] Now was the first album she wrote without Lange's involvement, identifying the procedure as a very important songwriting experience because "I needed to do it alone, to start ideas and finish them without relying on anybody else's opinion and direction.

[148] Her primary musical genre is considered to be country pop,[149] with AllMusic critic Stephen Thomas Erlewine declaring that she "Skillfully fus[ed] mainstream, AOR rock production with country-pop".

"[152] She cites Karen Carpenter,[135] Dolly Parton, Mickey Guyton, Taylor Swift, The Chicks, Wynonna Judd, and Kelsea Ballerini as some of the female country artists who inspire her.

[154] According to biographer Stephen Thomas Erlewine, most critics accused her of "diluting country with bland, anthemic hard rock techniques and shamelessly selling her records with sexy videos.

[135] Similar to Garth Brooks before her, she was initially branded an interloper whose modern production, presentation and songwriting "disrupt[ed] the genre's status quo".

[143][152] Despite the breakthrough success of The Woman in Me, early detractors did not take her seriously as an artist, with several music journalists questioning her lyrics, the "manufactured" production of her albums, and her singing ability.

[154][157] Early in her career she found herself at odds with the conservative opinions of the country music industry at the time due to her assertive personality and proclivity for wearing revealing outfits that exposed her midriff.

[156][158] The Independent's Roisin O'Connor believes "Nashville hadn't seen anything like Twain [before] – a leopard print-loving, midriff-exposing artist determined to be an international star.

[143] Refusing "to conform to a single archetype of femininity", she recalled that she used music to communicate with like-minded women by alternating between heartbroken, comedic, vengeful, empowered, self-deprecating and lustful personas "all on the same record.

[154] Sarah Koo of Entertainment Tonight Canada wrote that, in hindsight, Twain's image throughout the 1990s seems tame in comparison to the revealing outfits of artists who have since succeeded her.

[160] Journalist Brian D. Johnson wrote that, despite her girl next door image, Twain "has the sort of star power that people expect from royalty", which he attributes to her Cinderella-esque life story.

[160] BBC Online described her as "the real Queen of Pop", citing her influence on subsequent successful female artists such as Meghan Trainor, Britney Spears, Taylor Swift and Haim.

"[161] Justin Chandler of CBC credited her with making "country-pop crossover its own genre" and "paving the way for artists sitting atop those same charts every year since.

[159] She has been cited as a major influence among Canadian country music artists such as Tenille Arts, Jess Moskaluke, Dean Brody, Lindi Ortega and Brett Kissel.
