Question: Who is the author of the biography of the star that established herself as a Queen of Popular Music?

full_context: Document 1: Madonna (entertainer): Possessing a mezzo-soprano vocal range, Madonna has always been self-conscious about her voice, especially in comparison to her vocal idols such as Ella Fitzgerald, Prince, and Chaka Khan. Mark Bego, author of Madonna: Blonde Ambition, called her "the perfect vocalist for lighter-than-air songs", despite not being a "heavyweight talent." According to MSNBC critic Tony Sclafani, "Madonna's vocals are the key to her rock roots. Pop vocalists usually sing songs "straight," but Madonna employs subtext, irony, aggression and all sorts of vocal idiosyncrasies in the ways John Lennon and Bob Dylan did." Madonna used a bright, girlish vocal timbre in her early albums which became passé in her later works. The change was deliberate since she was constantly reminded of how the critics had once labelled her as "Minnie Mouse on helium". During the filming of Evita, Madonna had to take vocal lessons, which increased her range further. Of this experience she commented, "I studied with a vocal coach for Evita and I realized there was a whole piece of my voice I wasn't using. Before, I just believed I had a really limited range and was going to make the most of it."
Document 2: My Story (Dannii Minogue book): My Story is a memoir by Australian singer Dannii Minogue. Written in the United Kingdom and Australia with the help of long-time friend Terry Ronald, the book was released in September 2010 in the UK and in October 2010 in Australia.
Document 3: Madonna (entertainer): Madonna has received acclaim as a role model for businesswomen in her industry, "achieving the kind of financial control that women had long fought for within the industry", and generating over $1.2 billion in sales within the first decade of her career. Professor Colin Barrow from Cranfield School of Management described Madonna as "America's smartest businesswoman ... who has moved to the top of her industry and stayed there by constantly reinventing herself." London Business School academics called her a "dynamic entrepreneur" worth copying; they identified her vision of success, her understanding of the music industry, her ability to recognize her own performance limits (and thus bring in help), her willingness to work hard and her ability to adapt as the keys to her commercial success. Morton wrote that "Madonna is opportunistic, manipulative, and ruthless—somebody who won't stop until she gets what she wants—and that's something you can get at the expense of maybe losing your close ones. But that hardly mattered to her." Hazel Blackmore and Rafael Fernández de Castro in the book ¿Qué es Estados Unidos? from the Fondo de Cultura Económica, noted: "Madonna has been undoubtedly the most important woman in the history of popular music and a great businesswoman in herself; creating fashion, breaking taboos and provoking controversies."
Document 4: Madonna (entertainer): Various music journalists, critical theorists, and authors have deemed Madonna the most influential female recording artist of all time. Author Carol Clerk wrote that "during her career, Madonna has transcended the term 'pop star' to become a global cultural icon." Rolling Stone of Spain wrote that "She became the first viral Master of Pop in history, years before the Internet was massively used. Madonna was everywhere; in the almighty music television channels, 'radio formulas', magazine covers and even in bookshops. A pop dialectic, never seen since The Beatles's reign, which allowed her to keep on the edge of tendency and commerciality." Laura Barcella in her book Madonna and Me: Women Writers on the Queen of Pop (2012) wrote that "really, Madonna changed everything the musical landscape, the '80s look du jour, and most significantly, what a mainstream female pop star could (and couldn't) say, do, or accomplish in the public eye." William Langley from The Daily Telegraph felt that "Madonna has changed the world's social history, has done more things as more different people than anyone else is ever likely to." Alan McGee from The Guardian felt that Madonna is a post-modern art, the likes of which we will never see again. He further asserted that Madonna and Michael Jackson invented the terms Queen and King of Pop.
Document 5: Madonna (entertainer): Before emerging as a pop star, Madonna has spent her early years in rock music alongside her bands, Breakfast Club and Emmy. While performing with Emmy, Madonna recorded about 12-14 songs which resemble the punk rock of that period. Her early rock roots also can be found on the demo album Pre-Madonna. Stephen Thomas Erlewine noted that with her self-titled debut album, Madonna began her career as a disco diva, in an era that did not have any such divas to speak of. In the beginning of the '80's, disco was an anathema to the mainstream pop, and according to Erlewine, Madonna had a huge role in popularizing dance music as mainstream music. The album's songs reveal several key trends that have continued to define her success, including a strong dance-based idiom, catchy hooks, highly polished arrangements and Madonna's own vocal style. Her second album, Like a Virgin (1984), foreshadowed several trends in her later works. It contained references to classical works (pizzicato synthesizer line that opens "Angel"); potential negative reaction from social groups ("Dress You Up" was blacklisted by the Parents Music Resource Center); and retro styles ("Shoo-Bee-Doo", Madonna's homage to Motown).
Document 6: Madonna (entertainer): According to Tony Sclafani from MSNBC, "It's worth noting that before Madonna, most music mega-stars were guy rockers; after her, almost all would be female singers ... When The Beatles hit America, they changed the paradigm of performer from solo act to band. Madonna changed it back—with an emphasis on the female." Howard Kramer, curatorial director of the Rock and Roll Hall of Fame and Museum, asserted that "Madonna and the career she carved out for herself made possible virtually every other female pop singer to follow ... She certainly raised the standards of all of them ... She redefined what the parameters were for female performers." According to Fouz-Hernández, subsequent female singers such as Britney Spears, Christina Aguilera, Kylie Minogue, the Spice Girls, Destiny's Child, Jennifer Lopez, and Pink were like her "daughters in the very direct sense that they grew up listening to and admiring Madonna, and decided they wanted to be like her." Time magazine included her in the list of the "25 Most Powerful Women of the Past Century", where she became one of only two singers to be included, alongside Aretha Franklin. She also topped VH1's lists of "100 Greatest Women in Music" and "50 Greatest Women of the Video Era".
Document 7: Madonna (entertainer): Madonna's popularity was further enhanced by her film roles, including Desperately Seeking Susan (1985), Dick Tracy (1990), and Evita (1996); the latter earned her a Golden Globe Award for Best Actress. However, most of her other films have been panned by critics. Her other ventures include fashion design, writing children's books, and filmmaking. She has been acclaimed as a businesswoman, particularly after she founded entertainment company Maverick (including the label Maverick Records). In 2007 she signed an unprecedented US $120 million 360 deal with Live Nation.
Document 8: Madonna (entertainer): In The Madonna Companion biographers Allen Metz and Carol Benson noted that more than any other recent pop artist, Madonna had used MTV and music videos to establish her popularity and enhance her recorded work. According to them, many of her songs have the imagery of the music video in strong context, while referring to the music. Cultural critic Mark C. Taylor in his book Nots (1993) felt that the postmodern art form par excellence is video and the reigning "queen of video" is Madonna. He further asserted that "the most remarkable creation of MTV is Madonna. The responses to Madonna's excessively provocative videos have been predictably contradictory." The media and public reaction towards her most-discussed songs such as "Papa Don't Preach", "Like a Prayer", or "Justify My Love" had to do with the music videos created to promote the songs and their impact, rather than the songs themselves. Morton felt that "artistically, Madonna's songwriting is often overshadowed by her striking pop videos."
Document 9: Madonna (book): Madonna is a biography by English author Andrew Morton, chronicling the life of American recording artist Madonna. The book was released in November 2001 by St. Martin's Press in the United States and in April 2002 by Michael O'Mara Books in the United Kingdom. Morton decided to write a biography on Madonna in 2000. The release was announced in April 2001 by St. Martin's Press. President and publisher Sally Richardson described the biography to contain details about Madonna's ambitions, her relationships and her lifestyle.
Document 10: Madonna (entertainer): Madonna's use of sexual imagery has benefited her career and catalyzed public discourse on sexuality and feminism. As Roger Chapman documents in Culture Wars: An Encyclopedia of Issues, Viewpoints, and Voices, Volume 1 (2010), she has drawn frequent condemnation from religious organizations, social conservatives and parental watchdog groups for her use of explicit, sexual imagery and lyrics, religious symbolism, and otherwise "irreverent" behavior in her live performances. The Times wrote that she had "started a revolution amongst women in music ... Her attitudes and opinions on sex, nudity, style and sexuality forced the public to sit up and take notice." Professor John Fiske noted that the sense of empowerment that Madonna offers is inextricably connected with the pleasure of exerting some control over the meanings of self, of sexuality, and of one's social relations. In Doing Gender in Media, Art and Culture (2009), the authors noted that Madonna, as a female celebrity, performer, and pop icon, is able to unsettle standing feminist reflections and debates. According to lesbian feminist Sheila Jeffreys, Madonna represents woman's occupancy of what Monique Wittig calls the category of sex, as powerful, and appears to gleefully embrace the performance of the sexual corvée allotted to women. Professor Sut Jhally has referred to Madonna as "an almost sacred feminist icon."
Document 11: Madonna (entertainer): Madonna Louise Ciccone (/tʃɪˈkoʊni/; Italian: [tʃikˈkoːne]; born August 16, 1958) is an American singer, songwriter, actress, and businesswoman. She achieved popularity by pushing the boundaries of lyrical content in mainstream popular music and imagery in her music videos, which became a fixture on MTV. Madonna is known for reinventing both her music and image, and for maintaining her autonomy within the recording industry. Music critics have acclaimed her musical productions, which have generated some controversy. Often referred to as the "Queen of Pop", she is often cited as an influence by other artists.
Document 12: Madonna (entertainer): Madonna's music has been the subject of much analysis and scrutiny. Robert M. Grant, author of Contemporary Strategy Analysis (2005), commented that what has brought Madonna success is "certainly not outstanding natural talent. As a vocalist, musician, dancer, songwriter, or actress, Madonna's talents seem modest." He asserts Madonna's success is in relying on the talents of others, and that her personal relationships have served as cornerstones to the numerous reinventions in the longevity of her career. Madonna's approach was far from the music industry wisdom of "Find a winning formula and stick to it." Her musical career has been a continuous experimentation with new musical ideas and new images and a constant quest for new heights of fame and acclaim. Grant concluded that "having established herself as the queen of popular music, Madonna did not stop there, but continued re-inventing." Musicologist Susan McClary wrote that "Madonna's art itself repeatedly deconstructs the traditional notion of the unified subject with finite ego boundaries. Her pieces explore various ways of constituting identities that refuse stability, that remain fluid, that resist definition."
Document 13: Madonna (entertainer): Life with My Sister Madonna, a book by Madonna's brother Christopher, debuted at number two on The New York Times bestseller list. The book caused some friction between Madonna and her brother, because of the unsolicited publication. Problems also arose between Madonna and Ritchie, with the media reporting that they were on the verge of separation. Ultimately, Madonna filed for divorce from Ritchie, citing irreconcilable differences, which was finalized in December 2008. She decided to adopt from Malawi. The country's High Court initially approved the adoption of Chifundo "Mercy" James; however, the application was rejected because Madonna was not a resident of the country. Madonna appealed, and on June 12, 2009, the Supreme Court of Malawi granted Madonna the right to adopt Mercy James. She also released Celebration, her third greatest-hits album and final release with Warner. It contained the new songs "Celebration" and "Revolver" along with 34 hits spanning her career. Celebration reached number one in the UK, tying her with Elvis Presley as the solo act with most number one albums in the British chart history. She appeared at the 2009 MTV Video Music Awards on September 13, 2009, to speak in tribute to deceased pop star Michael Jackson.
Document 14: Madonna (entertainer): Throughout her career Madonna has been involved in writing and producing most of her own music. Madonna's early songwriting skill was developed during her time with the Breakfast Club in 1979. According to author Carol Gnojewski, her first attempts at songwriting are perceived as an important self-revelation, as Madonna said: "I don't know where [the songs] came from. It was like magic. I'd write a song every day. I said 'Wow, I was meant to do this'." Mark Kamins, her first producer, believed that Madonna is "a much underrated musician and lyricist." Rolling Stone has named her "an exemplary songwriter with a gift for hooks and indelible lyrics." According to Freya Jarman-Ivens, Madonna's talent for developing "incredible" hooks for her songs allows the lyrics to capture the attention of the audience, even without the influence of the music. As an example, Jarman-Ivens cites the 1985 single "Into the Groove" and its line "Live out your fantasy here with me, just let the music set you free; Touch my body, and move in time, now I know you're mine." Madonna's songwriting are often autobiographical over the years, dealing with various themes from love and relationships to self-respect and female empowerment. Her songs also speak about taboo and unconventional issues of their period, such as sexuality and AIDS on Erotica (1992). Many of her lyrics contain innuendos and double entendre, which lead to multiple interpretations among music critics and scholars. Madonna has been nominated for being inducted into the Songwriters Hall of Fame twice, for 2014 and 2016 ceremony. Rolling Stone listed Madonna at number 56 on the "100 Greatest Songwriters of All Time".
Document 15: Madonna (entertainer): Madonna gave another provocative performance later that year at the 2003 MTV Video Music Awards, while singing "Hollywood" with Britney Spears, Christina Aguilera, and Missy Elliott. Madonna sparked controversy for kissing Spears and Aguilera suggestively during the performance. In October 2003, Madonna provided guest vocals on Spears' single "Me Against the Music". It was followed with the release of Remixed & Revisited. The EP contained remixed versions of songs from American Life and included "Your Honesty", a previously unreleased track from the Bedtime Stories recording sessions. Madonna also signed a contract with Callaway Arts & Entertainment to be the author of five children's books. The first of these books, titled The English Roses, was published in September 2003. The story was about four English schoolgirls and their envy and jealousy of each other. Kate Kellway from The Guardian commented, "[Madonna] is an actress playing at what she can never be—a JK Rowling, an English rose." The book debuted at the top of The New York Times Best Seller list and became the fastest-selling children's picture book of all time.
