a certain point, the term ‘hook song’ became a word to negatively point out K-Pop idol groups songs’ addictive nature. In a hook song, its chorus is short and repetitive, making it easy for the listener to sing along without noticing. For example, Wonder Girls’ ‘Nobody’ and Girls’ Generation’s ‘Gee’ are hook songs, representing idol groups with hook songs. Those who are against hook songs believe that this type of music is detrimental to the variety of Korean music industry. They believe that these songs are focused on the dance more than the song, lowering the standard of artistry and musicianship.
