Question: When the performer who has had the most top ten hits drop out of college?

full_context: Document 1: Whitney Houston: Houston is the only artist to chart seven consecutive No. 1 Billboard Hot 100 songs. She is the second artist behind Elton John and the only woman to have two number - one Billboard 200 Album awards (formerly ``Top Pop Albums '') on the Billboard magazine year - end charts. Houston's self - titled debut album (1985) became the best - selling debut album by a woman in history. Rolling Stone named it the best album of 1986, and ranked it at number 254 on the magazine's list of the 500 Greatest Albums of All Time. Her second studio album, Whitney (1987), became the first album by a woman to debut at number one on the Billboard 200 albums chart.
Document 2: Madonna (entertainer): Besides singing Madonna has the ability to play several musical instruments. She learned to play drum and guitar from her then-boyfriend Dan Gilroy in the late 1970s before joining the Breakfast Club line-up as the drummer. This helped her to form the band Emmy, where she performed as the guitarist and lead vocalist. Madonna later played guitar on her demo recordings. On the liner notes of Pre-Madonna, Stephen Bray wrote: "I've always thought she passed up a brilliant career as a rhythm guitarist." After her career breakthrough, Madonna focused mainly in singing but was also credited for playing cowbell on Madonna (1983) and synthesizer on Like a Prayer (1989). In 1999, Madonna had studied for three months to play the violin for the role as a violin teacher in the film Music of the Heart, before eventually leaving the project. After two decades, Madonna decided to perform with guitar again during the promotion of Music (2000). She took further lessons from guitarist Monte Pittman to improve her guitar skill. Since then Madonna has played guitar on every tour, as well as her studio albums. At the 2002 Orville H. Gibson Guitar Awards, she received nomination for Les Paul Horizon Award, which honors the most promising up-and-coming guitarist.
Document 3: Madonna (entertainer): Madonna holds the record for the most number-ones on all combined Billboard charts, including twelve number-one songs on the Billboard Hot 100 and eight number-one albums on the Billboard 200.

She has also scored 38 top-ten singles on the Hot 100, more than any other artist in history. In 2008, Billboard magazine ranked her at number two, behind The Beatles, on the Billboard Hot 100 All-Time Top Artists, making her the most successful solo artist in the history of American singles chart.

Document 6: Madonna (entertainer): In 1978, she dropped out of college and relocated to New York City. She had little money and worked as a waitress at Dunkin' Donuts and with modern dance troupes, taking classes at the Alvin Ailey American Dance Theater and eventually performing with Pear Lang Dance Theater. Madonna said of her move to New York, "It was the first time I'd ever taken a plane, the first time I'd ever gotten a taxi cab. I came here with $35 in my pocket. It was the bravest thing I'd ever done." She started to work as a backup dancer for other established artists. Madonna claimed that during a late night she was returning from a rehearsal, when a pair of men held her at knifepoint and forced her to perform fellatio. Madonna later commented that "the episode was a taste of my weakness, it showed me that I still could not save myself in spite of all the strong-girl show. I could never forget it."
Document 7: Madonna (entertainer): Born in Bay City, Michigan, Madonna moved to New York City in 1977 to pursue a career in modern dance. After performing in the music groups Breakfast Club and Emmy, she signed with Sire Records (an auxiliary label of Warner Bros. Records) in 1982 and released her self-titled debut album the following year. She followed it with a series of commercially and critcally successful albums, including the Grammy Award winners Ray of Light (1998) and Confessions on a Dance Floor (2005). Throughout her career, Madonna has written and produced most of her songs, with many of them reaching number one on the record charts, including "Like a Virgin", "Into the Groove", "Papa Don't Preach", "Like a Prayer", "Vogue", "Frozen", "Music", "Hung Up", and "4 Minutes".
Document 8: Madonna (entertainer): Having sold more than 300 million records worldwide, Madonna is recognized as the best-selling female recording artist of all time by Guinness World Records. The Recording Industry Association of America (RIAA) listed her as the best-selling female rock artist of the 20th century and the second best-selling female artist in the United States, with 64.5 million certified albums. According to Billboard, Madonna is the highest-grossing solo touring artist of all time, earning US $1.31 billion from her concerts since 1990. She was ranked at number two, behind only The Beatles, on the Billboard Hot 100 All-Time Top Artists, making her the most successful solo artist in the history of American singles chart. Madonna became one of the five founding members of the UK Music Hall of Fame and was inducted into the Rock and Roll Hall of Fame in her first year of eligibility.
Document 9: Elvis Presley singles discography: Both of these claims were disputed by music historian Joel Whitburn and Elvis Presley Enterprises. Whitburn lists Elvis as having 18 number 1 hits (placing him in a tie with Mariah Carey at that time) and 38 top ten hits (one more than Madonna at that time). Elvis Presley Enterprises claims Elvis had 40 top ten hits. The differences depend on whether a double - sided hit single is counted as one hit single, or two hit songs.
Document 10: Madonna (entertainer): Madonna turned to her paternal grandmother for solace. The Ciccone siblings resented housekeepers and invariably rebelled against anyone brought into their home ostensibly to take the place of their beloved mother. Madonna later told Vanity Fair that she saw herself in her youth as a "lonely girl who was searching for something. I wasn't rebellious in a certain way. I cared about being good at something. I didn't shave my underarms and I didn't wear make-up like normal girls do. But I studied and I got good grades.... I wanted to be somebody." Terrified that her father Tony could be taken from her as well, Madonna was often unable to sleep unless she was near him.
Document 11: Madonna (entertainer): Madonna entered mainstream films in February 1985, beginning with a brief appearance as a club singer in Vision Quest, a romantic drama film. Its soundtrack contained two new singles, her U.S. number-one single, "Crazy for You", and another track "Gambler". She also played the title role in the 1985 comedy Desperately Seeking Susan, a film which introduced the song "Into the Groove", her first number-one single in the UK. Her popularity relegated the film as a Madonna vehicle, despite not having lead actress billing. The New York Times film critic Vincent Canby named it one of the ten best films of 1985.Beginning in April 1985, Madonna embarked on her first concert tour in North America, The Virgin Tour, with the Beastie Boys as her opening act. She progressed from playing CBGB and the Mudd Club to playing large sporting arenas. The tour saw the peak of Madonna wannabe phenomenon, with lots of female attendees dressing like her. At that time, she released two more hits, "Angel" and "Dress You Up", making all four singles from the album peak inside the top five on the Hot 100 chart. In July, Penthouse and Playboy magazines published a number of nude photos of Madonna, taken in New York in 1978. She had posed for the photographs as she needed money at the time, and was paid as little as $25 a session. The publication of the photos caused a media uproar, but Madonna remained "unapologetic and defiant". The photographs were ultimately sold for up to $100,000. She referred to these events at the 1985 outdoor Live Aid charity concert, saying that she would not take her jacket off because "[the media] might hold it against me ten years from now."

Document 13: 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 14: 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 15: List of artists by number of UK Singles Chart number ones: In addition to his number ones as a member of The Beatles, Paul McCartney has received an individual credit on three more (``Ebony and Ivory '',`` Pipes of Peace'' and ``Ferry Cross the Mersey ''charity record) and as a member of Wings (`` Mull of Kintyre'') as well as four more charity records (``Do They Know It's Christmas? ''by Band Aid and Band Aid 20,`` Let It Be'' by Ferry Aid and ``He Ai n't Heavy, He's My Brother ''by Justice Collective), making a total of 99 weeks at number one with 25 different singles, including the biggest selling single of the 1960s, 70s and 80s (`` She Loves You'', ``Mull of Kintyre ''and`` Do They Know It's Christmas?'').
