I thought it would be nice to have a thread that features K-pop songwriters, composers and producers talking about how of your favourite K-pop songs were made. So post here any videos / interviews you have found about how K-pop producers / songwriters created the songs you enjoy! This can also include idols talking about songs that they took part in writing the lyrics / composing the melody for.
