Guess which idol finally took the win on the May 13 broadcast of MBC's 'Duet Song Festival'!

On this day, Ken, Cho PD, Lee Ji Hye, Tim, Changmin, and Wendy stood up on stage to verse one another in duets partnered up with non-celebrity singers.  Sandeul won on last week, but he was unable to be on this episode to defend his crown (he'll be back for next week) due to his schedule, so he called in and introduced the first performer!  It turned out to be Cho PD and Cho Hyung Won performing DJ DOC's "The Beauty and the Beast" for a solid lead of 387 points.

Ken and Choi Sang Yup, whom people voted for three weeks consecutively as the duo they wanted to see again, took the stage once again, this time taking on Deulgukhwa's "That is My World."  They took the lead with 437 points!  Next, Changmin and Jun Gun Ho performed Baek Ji Young's "Don't Forget," and they got close - but unfortunately, only got 429 points.  Lastly, Lee Ji Hye and Pi Kyung Jin took on TaeTiSeo's "Twinkle" for the lowest score of 241 points.

In the end, Ken's team finally won!  Congratulations!  The team people most wanted to see again was then given to Changmin and Jun Gun Ho.
