Of course, many very old monster-level players with very old age and great duty, I will not mention it!
Most of the top actresses mentioned are popular and powerful and still active in front of the stage, of course, there are also ost singer-songwriters who are pure behind the scenes.
The reason why Kim Tae-yeon can be called a legend is that the OST sung by the other ost queens besides her is basically the OST of the popular Korean drama.
Although the singing skills are indeed praised, it has to be said that the popular series do have a good role in promoting OST.
The most legendary part of Kim Tae-yeon is that during her most difficult and dark period (2008 Black Sea), she sang a fairly ordinary interlude ("If") to a street drama ("Fast Knife Hong Ji Tong"), and then swept South Korea for half a year, and then sang a more undulating interlude ("Can You Hear") to another street drama ("Beethoven Virus"), which was popular for half a year.
"Fast Knife Hong Ji Tong"
After that, I sang a lot of good OST, so I won't list them all
Kim Tae-yeon OST
How much does the drama of "Fast Knife Hong Ji Tong" really hit the street? If you look at the plot setting and costume features, it's funny!
The script is still the Hong sisters', and then are they inextricably linked to Zhang Genshuo? Or was he just drunk under the jeans of the "eel"? There are more supporting roles than the protagonists, and the costumes and props of the supporting roles are estimated to be able to buy 100 sets of the protagonist! Even the big beauty Cheng Yuli can't save the ratings!
Cheng Yuli
It is conceivable that the ratings are super low, but the song "If" has won the love of the audience, swept South Korea, and radiated To Asia.
As the songwriter of "If" said, the song's lyrics can only be regarded as medium and high, and it is precisely because they have found the most suitable singer that the two have achieved each other and become an irreproducible art!
Speaking of "Beethoven Virus", the drama is really good, but the theme is too niche, so the ratings are not high, fortunately, "Can You Hear It" still won the love of the audience in Tae-yeon's emotional singing, and it is still popular at the time and the classic is still so far.
Beethoven Virus
Maybe Kim Tae-yeon isn't the best singer among Korean OST queens, but she's definitely the most legendary!
I highly recommend that you listen to the live versions of "If" and "Can You Hear", which is definitely an art that she cannot copy!
Kim Tae-yeon "If"
(Recommended to listen to the 2008 TV version)
There is also a live version of the concert of "I Love You", which is a masterpiece, and Kim Tae-yeon herself cannot copy the singing!
Kim Tae-yeon "I Love You"
I like what Tae-yeon said: "When you sing, you need skill and a little imagination." You should cherish your feelings and pour out your feelings wholeheartedly, without betraying the original color of the song. ”
