KBS once again banning some songs and ruled them unfit for broadcast. Not only one, but three Mad Clown's songs, “Gum,” “Kkeng Cost,” and “Stalker,” were banned. The other song by Mad Clown, “The Scent of Skin” also in review but it's postponed because one of the judge is absent. Then the remaining one song from Mad Clown's mini album which is currently allowed for broadcast is "Without You" featuring SISTAR's Hyorin. Eddy Kim's song "Slow Dance" also prohibited for broadcast by KBS.
The reason why “Gum” is banned because the lyrics contain brand name, ‘Mercedes’. Meanwhile “Kkeng cost,” is a slang expression referring to someone overplaying an injury for money. Then “Stalker” is banned because of the bad meaning of the word.
Similar case to Eddy Kim’s “Slow Dance” its banned because of it mention a vodka brand, Grey Goose.
Both Mad Clown and Eddy Kim decided not to change the lyrics and just leave it as it is.
