Curiouser

Miller-Heidke explains the album's title: "Mickey (Petralia) thought "Curiouser" was a noun, something that made you more curious," she said. "That's what made up my mind about the title. Wouldn't it be great if people listened to this album and it made them curiouser?".^[7]

All songs written by Kate Miller-Heidke and Keir Nuttall, produced by Mickey Petralia and Keir Nuttall.

• "Can't Shake It"

Can't Shake It was released to the radio in late 2008, and became the #1 most added track to the radio in its first week^{[citation needed]}. It debuted and peaked on the ARIA Singles Chart at #38. It was used as part of a television advertisement for the radio station NOVA, and as a result, received extensive air play across Australia. Can't Shake It is Miller-Heidke's 3rd best selling single to date.^{[citation needed]}

• "Caught in the Crowd"

Was highly speculated as the 2nd single in December 2008, as it was getting decent airplay on Triple J. Then it was officially released to radio on 9 February 2009. It was released on 20 February as a physical CD, and coincided with the national tour Miller-heidke embarked on in early 2009.^{[citation needed]} The music video was directed by Stephen Lance and Mairi Cameron. The song also won Miller-Heidke the overall grand prize (US$25,000 in cash and US$20,000 worth of musical equipment, among other prizes) of the prestigious "International Songwriting Competition" 2009 (ISC).^[8] Following the success, Caught in the Crowd was released as a Digital Single, with a new song "Are You F***ing Kidding Me", exclusively on iTunes. On 13 November, it was re-released as the 4th single from Curiouser. Caught in the Crowd has gained Gold accreditation in Australia.^{[citation needed]}

• "The Last Day on Earth"

Was not initially released as a single, but has since reached #3 on the Australian ARIA Singles Chart. The song was used for promotions for the block of episodes from the Australian soap opera Neighbours which surrounded the death of Bridget Parker in early July 2009. This in turn caused high sales of the song from her Curiouser album. Due to the high demand for the song, a physical single was quickly produced, and was released on 14 July 2009. The song ended up becoming Kate's first top ten single. "Miller-Heidke" stated that no 3rd single was ever planned. The Last Day on Earth has gone 2× platinum in Australia as of March 2010.^{[citation needed]}
