Kim Jong Kook's new song was played at the end of a recent episode of "Running Man."

The recent episode of "Running Man- Super Match" that aired on Sunday featured the cast members holding a match in the mud. Moon Geun Young and TVXQ appeared as guests. Moon Geun Young's team won on the latest episode. 

As the offensive team was winning, Kim Jong Kook's song seemed to be playing in the background and gained the interest of viewers. People seemed to be asking if that was Kim Jong Kook's new song. 

Kim Jong Kook is to release his 7th album in the end of October. He will reveal the first half of his album on October 23, to return as a singer, and the rest will be revealed after.
