Question: Drowned World Tour was in support of which 2000 Madonna album?
Context: "Bedtime Story" is a song recorded by American singer Madonna for her sixth studio album, "Bedtime Stories" (1994).  It was released as the third single from the album on February 13, 1995, by Maverick Records, and it also appears on Madonna's compilation album "GHV2" (2001).  "Bedtime Story" was written by Björk, Nellee Hooper and Marius De Vries; it was the only time Björk wrote a song for a Madonna album.  She re-wrote a demo of the song to the current version, which was then produced by Madonna and Hooper.  A mid-tempo electronic and house song with acid, ambient and techno influences, "Bedtime Story" has an underlying skeletal synth melody influenced by minimal trance music.  The track was a departure from Madonna's pop-R&B-based outputs in favor of unconventional and electronic music.  Lyrically it talks about the joys of the unconscious world. American singer Madonna has embarked on ten concert tours, nine of which have been worldwide.  Her 1985 debut, The Virgin Tour, was based in North America only and was critically panned but went on to collect more than US $5 million.  In 1987 she performed on the worldwide Who's That Girl World Tour, which visited Europe, North America and Japan.  It was critically appreciated for Madonna's showmanship and "exquisite" dresses.  She embarked on the Blond Ambition World Tour in 1990, which Don Shewey of "Rolling Stone" called "the best tour of [the year]".  The performances featured Madonna simulating masturbation during "Like a Virgin".  Officials in Toronto threatened to arrest her unless she removed the masturbation sequence, and in Italy, the Pope called for a boycott.  In 1993, Madonna visited Israel and Turkey for the first time, followed by Latin America and Australia, with The Girlie Show World Tour.  Madonna opened the show dressed as a whip-cracking dominatrix, surrounded by topless dancers of both sexes.  A review in "Time" by Sam Buckley said: "Madonna, once the Harlow harlot and now a perky harlequin, is the greatest show-off on earth." "Drowned World/Substitute for Love" is a song recorded by American singer Madonna for her seventh studio album, "Ray of Light" (1998).  It was written and produced by Madonna and William Orbit, with additional songwriters including Rod McKuen, Anita Kerr and David Collins.  McKuen and Kerr received the credits due to the usage of a sample from one of their songs, "Why I Follow the Tigers".  "Drowned World/Substitute for Love" is an ambient pop ballad, which includes trip hop, electronica and minor guitar riffs towards the end.  Lyrically, the track describes Madonna's spiritual transformation to seek authentic love over superficial alliances. GHV2 (an abbreviation of Greatest Hits Volume 2) is the second greatest hits album by American recording artist Madonna.  Maverick and Warner Bros.  Records released it on November 12, 2001, coinciding with the video album, "Drowned World Tour 2001".  A follow-up to "The Immaculate Collection" (1990), "GHV2" contains a collection of singles during the second decade of Madonna's career.  Madonna mentioned that she only included "songs that I could listen to five times in a row" on it.  The album did not contain any new songs, but a promotional single, "GHV2 Megamix", was released to promote it, with remixes by Thunderpuss, John Rocks & Mac Quayle and Tracy Young.  Another promotional remix album was released alongside, titled "GHV2 Remixed: The Best of 1991–2001". Music is the eighth studio album by American singer Madonna, released on September 18, 2000 by Maverick and Warner Bros.  Records.  Following the success of her previous album "Ray of Light" (1998), she intended to embark on a tour.  However, her record company encouraged her to return to the studio and record new music before going on the road.  Her collaboration with producers Mirwais Ahmadzaï and William Orbit resulted a more experimental direction for the album.  "Music" has an overall dance-pop and electronica vibe, with influences from rock, country and folk.  The album was mostly recorded at Sarm West and East Studios in London, England.  Elaborating a country theme for the album, Madonna reinvented her image as a cowgirl. Drowned World Tour 2001 is the fifth video album by American singer and songwriter Madonna.  It was released on November 13, 2001, by Warner Music Vision, Warner Reprise Video, and Maverick Records to accompany Madonna's second greatest hits album "GHV2".  The video chronicles a live date from Madonna's Drowned World Tour, which visited Europe and North America, grossing over US $76.8 million ($ million in 2016 dollars) in total.  It was recorded at The Palace of Auburn Hills in Auburn Hills, Michigan on August 26, 2001 and was originally broadcast live on HBO as "Madonna Live!  Drowned World Tour 2001". The Girlie Show World Tour (also referred to as simply The Girlie Show) was the fourth concert tour by American singer and songwriter Madonna, in support of her fifth studio album, "Erotica".  The tour visited the Americas, Europe, Asia, and Australia for the first time, selling 360,000 tickets in this leg only.  Madonna's inspiration for the name of the tour was a painting called "Girlie Show" by Edward Hopper.  The tour is estimated to have grossed over US$70 million.  Two separate television specials were broadcast during the tour, one made during the Japanese leg of the tour and shown only on Japanese television; "Madonna Live in Japan 1993 – The Girlie Show" and an HBO special "" which was later released in 1994 by Warner Music Vision on home video. The Rebel Heart Tour was the tenth concert tour by American singer Madonna, and was staged in support of her thirteenth studio album, "Rebel Heart".  Comprising 82 shows, the tour visited North America, Asia, Europe, and Oceania.  It began on September 9, 2015, in Montreal, Canada, at the Bell Centre and concluded on March 20, 2016, in Sydney, Australia at Allphones Arena.  It was officially announced on March 1, 2015, through Madonna's website and was led by Live Nation Entertainment's Global Touring Division, helmed by Arthur Fogel; this was the fifth collaboration between Madonna and Live Nation as well her third tour to be promoted by the company.  An all-arena tour, the Rebel Heart Tour visited cities where the singer has not performed before, and was her first to visit Australia since The Girlie Show World Tour (1993) more than 20 years prior. Who's That Girl: Original Motion Picture Soundtrack is the first soundtrack album by American singer and songwriter Madonna.  It was released on July 21, 1987 by Sire Records to promote the film of the same name.  It also contains songs by her label mates Scritti Politti, Duncan Faure, Club Nouveau, Coati Mundi and Michael Davidson.  The soundtrack is credited as a Madonna album, despite her only performing four of the nine tracks on the album.  After the commercial success of her film "Desperately Seeking Susan" (1985), Madonna wanted to act in another comedy film titled "Slammer", about a woman named Nikki Finn who was falsely accused of homicide.  However, due to the critical and commercial failure of her adventure film "Shanghai Surprise" (1986), Warner Bros. were initially reluctant to green light the project, but later agreed, after Madonna convinced them and also because they wanted to cash in on Madonna's success with soundtracks. Drowned World Tour was the fifth concert tour by American singer-songwriter Madonna in support of her seventh and eighth studio albums "Ray of Light" and "Music".  It was also her first tour in eight years, following The Girlie Show World Tour in 1993.  The tour was supposed to start in 1999, but was delayed until 2001 as Madonna gave birth to her son, got married to Guy Ritchie, was working on "Music", and was busy filming "The Next Best Thing".  When the tour was decided, Madonna appointed Jamie King as choreographer and the tour was planned in a short timespan of three months, including signing up the dancers, musicians and technicians.  Designer Jean-Paul Gaultier was the costume designer who designed the costumes in such way that they indicated different phases of Madonna's career.  The poster and logo for the tour included references to Kabbalah, which Madonna studied.
