Shinsadong Tiger revealed the story behind why he had given up on being a singer on 'Person Q'.

He began, "When I was 21, I once went into the recording studio to record as a singer. But as always, I just did the chores. Even though I should have been in the center of the recording studio directing the recording, it ended with me just doing everyone's chores and the recording session had ended before I even got to record. Everyone else directed, and I cleaned up the pet dogs' droppings."

He further revealed, "There were times when my songs would be released under someone else's name. I thought, 'Do I have to do this? Do I really have to go through this? Should I continue on? Then this is too hard.'"

Although he folded his dreams of becoming a singer, he decided to use his musical talents in a different way and ended up writing some of the biggest hits for many of today's popular idol groups, becoming one of the top composers in the Korean music scene.
