Isn't Lee Sun-hee an incredibly good singer in her own right?

Sometimes when I look at the comments here, people say she just has great volume or that she uses a "Labor Party" singing style.
I suppose if you only look at her performances from the 80s, you might feel that way,
but when you listen to her singing from the 2000s onwards, I don't feel that way at all, even regarding the finer details.
Furthermore, "Inyeon" and "Among Those" are hits that have transcended generations,
and you can't rank in the top 10 of the annual charts in the 2010s just by having great volume.
Also, if you listen to her singing or covering songs like Kim Gun-mo's "Wrongful Encounter,"
maybe because she is an older singer, the only thing is that her vibrato is a bit excessive,
but in terms of technical aspects like pitch, rhythm, and diction, everything seems to be top-tier.
People can say she isn't their taste, but I think it's correct to say she is an incredibly good singer.
