[1] She is best known as a member of the Swedish girl group Play, and she was in a collaborative project with White Lies bassist Charles Cave titled K.I.D.S.
Munter's first introduction to stardom, prior to joining Play, was at the age of 12, with the supporting role of Petra in the successful Swedish film Eva & Adam – Fyra Födelsedagar och ett Fiasko, directed by Catti Edfeldt.
The album peaked at number 74 on the Billboard Top 200[1] and their debut single, "Us Against the World", found success on Radio Disney and Nickelodeon.
After nearly a year hiatus, it was officially reported in October 2003 that Faye had left the group, and was replaced by Janet Leon, a 13-year-old singer from Gothenburg.
[8] To promote the Stadium Status, Munter and Kocky performed on various Swedish television programs including the morning news show Nyhetsmorgon.
[11] On 22 August 2010 Munter released the single (and subsequent music video) "Waterfall"[11] which was produced and co-written by Jim Eliot (Kylie, Ladyhawke).
"[11] Munter described her sound as "big emotional, chaotic, beautiful pop"[12] while The Guardian has described her debut single "Waterfall" as "gorgeously gloomy sugar-pop" and "Sylvia Plath in American Apparel.
"[13] Throughout 2010 and 2011, Munter formed and performed with a DJ collective called XOXO with her friends Malin Cumzelius, Aino Neneh Jawo, and Caroline Hjelt.
"[14][non-primary source needed] Along with friend Charles Cave, Munter debuted a new collaborative project at South by Southwest in March 2013.
[16] Nylon has described the band's sound as "dark-edged electro-pop"[17] while Idolator has described their material as "rich and dramatic, avoiding overwrought theatricality thanks to an expert sense of sonic balance: driving bass grooves and moody, billowy synth textures underpin Rosanna’s sweetly inviting vocal melodies."
In early 2015 Munter started a management company called Logic & Heart and has since then worked with artists such as Icona Pop and Lune and producer/songwriter Elias Kapari.
