"Mistake" was written by Tom Nichols, Rami, and Arnthor Birgisson and produced by the latter two at Maratonem with mixing handled by Niklas Flycht.

The music video features Ryan Carnes, who acts on Desperate Housewives, a show of which McIntosh is a fan.

It premiered on Video Hits on the morning of 1 July 2006, and it was available to view on her official website.

[citation needed] The opening scene starts with McIntosh dumping her boyfriend and walking up to a house singing.

She sings into the mirror and takes off her white shirt, revealing a green blondie T-shirt.

They then walk into the main party area with the man leading her to an unknown place.
