KBS's 'Immortal Song 2' broadcasted its 15th episode on September 10th! The rundown of 'Immortal Song 2' is that each contestant sings unique covers, just like on 'I Am a Singer'; however, there are no eliminations to pressure them. The six castmates will instead battle for pride, as the first place winner will be judged by a studio audience. Not only that, but they'll also receive priceless pointers and tips from the original artists of the songs they cover. This week's mission was to perform an adaptation of legendary hit songs by Nam Jin. With fresh new re-arrangements by the six idols, the audience members and Nam Jin himself were utterly captivated with the potential they showed.
