On the 15th of March, Koivunen made it into the fourth round of competition, singing the Whitesnake hit, "Here I Go Again". Despite some criticism from the judges for singing only heavy metal songs in the finals, Koivunen was unperturbed. "I don't see any reason to consider what people might like, since it seems they like the same thing I do," said Koivunen. At the end of the evening, Koivunen, the six other Idols finalists, and three of the semifinalists were presented with gold records for their album "Idols 2007", which sold over 15,000 copies in the two days after its release.
