1994–2001: Aqua and Aquarium

In 1994, Nystrøm was working as a singer on the Norwegian cruise ship MS Peter Wessel and was spotted by musician René Dif.^[3] He recruited her as lead singer for the music group Joyspeed, later renamed Aqua. The group consisted of vocalists Nystrøm, Dif along with Søren Rasted and Claus Norreen. In 2001, the band split.^[4]

2002–2006: Solo career and Play With Me

After the breakup of Aqua, Nystrøm continued as a soloist. In 2003, she released her first album Play with Me. It marked a change in her musical style, from the bubblegum sound of Aqua to a more R&B-influenced style. It reached number 30 on Denmark's Hitlisten chart^[5] and 74 on Norway's VG-lista chart. The album single "Virgin Superstar" was given some radio airplay, but did not chart and was not released. Her debut single "It's Your Duty" was released on 8 September. It peaked at number 3 on Denmark's Hitlisten chart and number 9 on Norway's VG-lista chart.^[6]

In 2004, she released the second single "Pretty Young Thing", a cover of Stella Soleil, which did not chart. She released a third and fourth single as limited vinyl promos of a cover version of "Here We Go", which originally was performed by Moonbaby, and "Scream" to DJs and radio stations. The song "We Wanna Party", which Nystrøm recorded and co-wrote with Xenomania, appeared on Girls Aloud's 2008 album Out of Control. Nystrøm and Xenomania co-wrote two more Girls Aloud songs, the tracks "No Good Advice" and "You Freak Me Out", which appeared on the Girls Aloud debut album Sound of the Underground. "No Good Advice" became a breakout hit for the group. In 2005, Nystrøm provided guest vocals on the LazyB single "I Love N.Y." and as part of charity project Giv Til Asien on the single Hvor små vi er, which peaked at number 1 at Danish single charts.^[7]

2007–present: Aqua reunion

On 26 October 2007, Nystrøm reunited with the other members of Aqua, and solicited opportunities for a single summer concert tour. After fielding offers by record companies in Denmark, Canada, United States, and United Kingdom, they settled with an eight concert tour in Denmark as part of the 2008 Grøn Koncert festival. After the big success of the summer concert, Nystrøm continued with work with Aqua and released a new track, "Back to the 80s", on 25 May 2009. They released their greatest hits album on 15 June, which featured the track, along with sixteen remastered tracks and three other new songs, "My Mamma Said", "Spin Me a Christmas" and "Live Fast, Die Young". From May to August, they toured Scandinavia and performed at several gigs in Germany, the UK, and France.^[8]

The greatest hits CD was released in North America and many European countries on 22 September, and in the UK on 29 September. In 2009, Nystrøm had a major role in the 2009 film Deliver Us from Evil under Danish director Ole Bornedal.^[specify] On 14 March 2011, Aqua released the single "How R U Doin?". They released the album Megalomania, on 3 October.
