39 Korean music critics selected the greatest singer of our time.
10 Lim Jaebum, who has not promoted for 10 plus years
8. Lena Park, no new hits for who knows how long and not even a Korean
8(tie) Lee Seungchul. No new hits for quite a while
Tied at 6 - Lee Sora and Kim Gunmo, whose better days are long gone
3. Kim Kwangsuk, deceased
2. Lee Mija, in 80s
1. Cho Yongpil, in 70s
In other words, this bunch of music critics, who direct the opinion of popular music among those who are older and better learned, rank the old relics, has beens and a corpse for "The Greatest Singer of Our Time".
Such are where the 'Opinion Leaders" of Korea stands at, simply ignoring idols outright.
IU was ranked at #5, but since #1-4 are not likely to release a relevant song now, she is effectively at #1.
These music critics do not see all the achievements of the KPop acts.
Which is why the older gen of Koreans are not likely to support KPop no matter how much success it might bring.
