Spears has scored six number-one albums on the Billboard 200. She also has four solo number-one singles on the US Billboard Hot 100: ". . . Baby One More Time", "Womanizer", "3", and "Hold It Against Me". As a featured artist, the "S&M" remix also topped the Billboard chart. Other singles, "Oops!. . . I Did It Again", "Toxic", and "Scream & Shout", topped the charts in most countries. With "3" in 2009 and "Hold It Against Me" in 2011, she became the second artist after Mariah Carey in the Hot 100's history to debut at number one with two or more songs. Spears's self-made heavily choreographed videography is considered a focal point to the success of her career, such as the image-redefining music video for "I'm a Slave 4 U". For this, she has been awarded the Michael Jackson Video Vanguard Award as praise for her provocative boundaries-pushing art in young female entertainment. She has earned numerous awards and accolades, including a Grammy Award; thirteen Guinness World Records; six MTV Video Music Awards; seven Billboard Music Awards, including the Millennium Award; the inaugural Radio Disney Icon Award; and a star on the Hollywood Walk of Fame.
