The single was released on March 9, 2009 by Universal Music as a digital download exclusive to the United Kingdom.

The single includes a new song (also available on the My Winter Storm Fan Edition) called "Wisdom of Wind".

The song was composed by Jeff Rona and Lisa Gerrard, and recorded in China.

A music video for "Enough" was intended to be filmed following the South American tour, but because the director was in a car accident, its release was canceled.

In September 2008, a preview of the video appeared on YouTube, with Tarja singing in front of a green screen.
