By the time of its release Kirschner abandoned the innocent romantic image of a former beauty queen by including explicitly sexual lyrics in several songs featured in the album and appearing topless on the title page of the Kankán magazine.

[4] V cudzom meste was an undisputed success, four of the songs featured on it became big hits that dominated the national charts and established Kirschner as the "queen" of pop music in Slovakia.

While her solo work failed to reach the hights of V cudzom meste, Kirschner received much acclaim for her collaborations with predominently Czech musicians.

In 2002 she released the single Bude mi lehká zem together with the composer and singer Petr Hapka, which became one of her most recognizable songs and introduced Kirschner to the Czech audience.

[9] Building on the success of this collaboration, she appeared in several songs of Hapka's 2006 album Strážce plamene including a duet První noc v novém bytě together with the legendary Czech folk singer Jaromír Nohavica.

[10] Deviating from her image as a pop singer, she teamed up with jazz musicians Peter Lipa and Boboš Procházka to record a blues album Eosphoros in 2005.

The album received good reviews and was supported by a series of live performances, including one in the Queen Elizabeth Hall in London.

[12] In spite of the lack of success with international audience, Kirschner retained her popularity at home, winning the OTO Awards for best female singer in 2008, 2009, 2010.

[17] In 2018, Kirschner started a collaboration with the band Para, resulting in the single Našou krajinou, followed by Pre tých, čo zostali in 2023.

[20] By the late 2010s, Kirschner became engaged in civil activism, becoming the face of ecological initiatives[21] and headlining the memorial concert for the murdered journalist Ján Kuciak.
