The "Prince of Ballads"�Sung Shi Kyung made a triumphant comeback on tonight's episode of�'M! Countdown'! Being away for three long years,�Sung Shi Kyung showed that time hasn't dulled any of his talents, as he smoothly delivered rich vocals for both "Oh My Goddess" and "I Like". Composer Hwang Se Joon commented, "'Oh My Goddess' can only be sung by Sung Shi Kyung. It's a song just for him. After "Smile Angel", the ballad singer hasn't done an upbeat track, so 'Oh My Goddess' is another opportunity to see Sung Shi Kyung's rhythm on stage. It's a fun song."
