Kim Jang Hoon has this voice that is immediately recognizable to those who listen to Korea music. It helps that he has put put 20+ albums over his career. In any case, one of the other reasons is the way that he has always portrayed himself in the media. May it be by donations to various organizations/causes, or being there for his Hoobaes who needed a little bit of help.
The channel has “살고싶다”, as translated as being “Be Alive”. I think I would say the literal translation of “I want to live”, shows the meaning better. To overcome, to encourage. Anyway, the song was quite nice, and it was interesting to see English translations along with it.
