Winner Ari Koivunen signed to Sony BMG and his coronation song "On the Top of the World" hit number 1. However, his debut album, "Fuel for the Fire", released in May 2007 was entirely composed of heavy metal material, Koivunen's signature style. The album was a huge success, debuting at number 1 and remaining there for a huge twelve consecutive weeks. "Fuel for the Fire" sold over 71,000 copies and received a double platinum certification. Koivunen's second album Becoming came in June 2008 and it too entered the chart at number 1; however it held the spot for only a single week and its success did not come near that of its predecessor, selling 17,000 units. Later in 2008 it was announced that Koivunen had become the new lead singer of Finnish heavy metal group Amoral. His first album with them, "Show Your Colors", was released in May 2009 and peaked at number 19, selling 2,000 copies to date.
