American singer Madonna has released 14 studio albums, three soundtrack albums, six live albums, seven compilation albums, and 38 other limited releases. Recognized as the world's best-selling female recording artist of all time by the Guinness World Records, Madonna has accumulated a total record sales of more than 300 million units worldwide. In their 2006 press release, the International Federation of the Phonographic Industry (IFPI) confirmed that Madonna's albums alone had sold over 200 million copies worldwide. She is ranked by the RIAA as the best-selling female rock artist of the 20th century and third highest-certified female artist in the United States, with 64.5 million album units. She holds the all-time record for the most number-one albums by a female artist in major music markets such as Australia, Germany, and the United Kingdom. In 1982, Madonna signed a recording contract with Sire Records, a label owned by Warner Bros. Records. The first release under the label was her self-titled debut album, Madonna (1983). It peaked at number eight on the Billboard 200 and was certified five-time platinum by the RIAA. She followed the debut album with Like a Virgin (1984), which became her first chart-topper in various countries and was certified diamond by the RIAA. Her third studio album, True Blue (1986), reached number one in a record-breaking 28 countries and was once named the best-selling album by a woman of all time by the 1992 edition of Guinness World Records. During 1987, she released two albums that reached platinum status in the United States: the Who's That Girl soundtrack and her first remix compilation, You Can Dance. Madonna's fourth studio album, Like a Prayer (1989), made her the woman with most Billboard 200 number-one albums of the 1980s (second overall, behind only Bruce Springsteen). Madonna entered the 1990s with the release of I'm Breathless (1990), which contained songs from and inspired by the film Dick Tracy, and her first greatest hits compilation, The Immaculate Collection (1990). The latter became her second diamond-certified album in the US and remains the best-selling compilation album by a solo artist with global sales of over 30 million units.
