[citation needed] By her late teens, she still had not really thought of continuing her music career – she had her heart set on managing Woolworths – until she won a spot on The Northern Composure CD and national songwriting competitions.

Horsnell has also managed many Australian tours, often with her band "the Inflatable Girlfriends" (ironically made up of male musicians), as support for The Frames, Josh Pyke, Bernard Fanning (Powderfinger), Lou Rhodes (Lamb) and Jason Mraz.

She has supplied vocals for several songs used in television commercials, including McHappy Day, Johnnie Walker, Huggies, Women's Weekly, Bonds (company) and National Grid plc (in the United States).

In 2008 Horsnell went back into the studio with producer Paul Mckercher (Augie March, Magic Dirt, Little Birdy, Eskimo Joe) to lay down 12 new tracks for her album Complicated Sweetheart.

[citation needed] The Cloud Appreciation Society, released in 2013, shares heartbreaking songs of small town love and loss, glows with an acoustic stripped-back sound, and is intermingled with Horsnell's quintessential starry-eyed voice, lyrics to die for and a delicate but timeless presence, which has made her so adored on the scene.
