The second season of Swedish Idol premiered in August 2005 and continued until its grand finale on 2 December, when 17-year-old Agnes Carlsson from Vänersborg was crowned winner. The series was the first to crown a female Idol and is to date the sole season to be won by either a public or judges' wildcard contestant. Of the over 120 Idol winners worldwide, Carlsson is one of only three who gained a place in the finals as a judges' wildcard. The others are 2003 Canadian Idol winner Ryan Malcolm and 2007 Australian Idol winner Natalie Gauci. Carlsson has since become the most successful recording artist in the show's history.
Top 24<br>Format: Two out of six semi-finalists made it to the live finals each day, based on public phone voting. Two additional semi-final contestants who had not initially gained enough votes were also chosen by the public to advance to the finals, along with a wildcard chosen by the judges as in Season 1.
