KBS's 'Immortal Song 2' broadcasted its 13th episode on August 27th! The rundown of 'Immortal Song 2' is that each contestant sings unique covers, just like on 'I Am a Singer'; however, unlike 'I Am a Singer', there are no eliminations to pressure them. The six castmates will instead battle for pride, as the first place winner will judged by a studio audience. Not only that, but the contestants will also receive priceless pointers and tips from the original artists of the songs they cover. This week's mission was to perform covers of legendary hit songs by Kim Wan Sun. With fresh new re-arrangements by the six idols, the audience members and Kim Wan Sun herself were utterly captivated with the potential they showed. Check out the performance cuts below, and tell us your favourite! === === Kyuhyun was announced as the winner for this episode.
