There are many music chart-topping programs in South Korea, where singers release new songs to hit the charts and perform new singles live, such as "Inkigayo", "Music Bank" and "M!" countdown". Many programs are live broadcast, and the audience can vote for their favorite singer in real time. If the singer ranks first in the overall vote at the end of the program, then he will be the "one" of this program. There are also some music websites and TV show lists. No matter what form they are in, as long as the singer is ranked first, then he is "one". In short, it is the first one. The first place is the popularity and the proof of the quality of the song. I am satisfied with the adoption~
