After being tested by him, Sohyang released her first single and then went on a tour with Jo Hwan-gon and participated in many concerts and musical performances.

[12][13] In Disney's movie Moana, Sohyang provided the singing voice of the protagonist in the Korean-dubbed version.

[18] She was given a special stage on which to perform the main OST "Wind Song" at the KBS Drama Awards on the last day of 2017.

[20][21] She became the King of the show with the highest number of consecutive wins ever achieved as a female contestant at that time.

During the 2018 Winter Olympics in Pyeongchang, ice dancer Yura Min and Alexander Gamelin performed to Sohyang's rendition of "Arirang Alone".

[22] Furthermore, during the opening ceremony of the 2018 Winter Paralympics in Pyeongchang Sohyang performed, together with Sumi Jo, the song "Here as One", which they both recorded specifically for this occasion.

She has said that she used to listen to artists Mariah Carey, Whitney Houston, and Celine Dion often, whose music helped her to get through these difficult times.

Sohyang was the first female singer to ever achieve 6 consecutive victories at that time and therefore set a new record, which was later broken by Son Seung-yeon ("The East Invincibility").
