According to KBS' review of recently released K-pop songs on the 9th, Mad Clown's "Gum", "The Smell of Your Skin", "Ggang-Gab", and "Stalker" and Eddy Kim's "Slow Dance" were deemed inappropriate for broadcast. 

"Gum" makes a reference to brand name 'Mercedes' in its lyrics and "Ggang-Gab" used coarse language. "Stalker" was also deemed unsuitable due to the curses and swearing in the lyrics. However, the title track "Without You" passed with flying colors. The decision on "The Smell of Your Skin" is currently deferred.

Eddy Kim's "Slow Dance" was deemed unfit for the mention of 'grey goose' in its lyrics which is an actual name of a vodka brand. However, his other tracks "It's Over", "Sober Up", and "The Manual" all passed the requirements.
