Taeyeon was discovered in the 2004 SM Entertainment‘s 8th Annual Best Contest winning Best Singer 1st Place & Grand Award in the contest. In 2004, she was featured in The One’s song “You Bring Me Joy” before debuting as Girls’ Generation’s leader. She is a 2008 graduate of Jeonju Art High School and was awarded the school’s Lifetime Achievement Award.
Tae-yeon has contributed to a couple of soundtracks as a solo artist, singing the theme song “Manyageh” (“만약에”, “If“) for the KBS2 drama Hong Gil Dong and “Deullinayo” (“들리나요”, “Can You Hear Me“) from the Beethoven Virus soundtrack. “If” became popular[clarification needed] on various online charts, around the same time “Baby Baby” was released, while “Deullinayo” received the YEPP Popularity award at the 2008 Golden Disk Awards.
She also sang “SarangInGulYo” (“사랑인걸요”, “It is love“) with Sunny for the drama Heading to the Ground, and the “S.E.O.U.L.” song with members of Super Junior and Girls’ Generation to promote South Korea. She also sang the song for Caribbean Bay / “Cabi” with her fellow members Jessica, Seohyun, Tiffany and Sunny with 2PM.
She sang a duet song with her mentor The One, called “Like a Star” which was released on November 17, 2010. She also sang in the soundtrack of SBS’s Athena:Goddess of War, with the song “I Love You“. The song was released on 13 December 2010. The song took number 1 in some hit charts.
On March 28, 2012, Tae-yeon sang and released “Missing You Like Crazy”, for the Korean Melodrama The King 2 Hearts starring Lee Seung-gi and Ha Ji- won, which took Number 1 on all charts such as Melon, Naver, Mnet, Soribada, Bugs, Olleh and Daum, achieving an ‘All Kill’ on the online charts on the day of its release. Tae-yeon had previously declined the offer to sing the OST for the drama due to her busy overseas schedules with Girls’ Generation, but later took it up as she had made a promise with PD Lee Pil-ho, the producer of “Beethoven’s Virus”, for which Tae-yeon also sang the OST. PD Lee Pil-ho also stated that when he had first received the synopsis for “The King 2 Hearts”, he had made special requests to only Tae-yeon, stating that she was the only singer who could sing the OST for the drama. In 2012, Tae-yeon also sang an OST, “Closer“, for the drama To the Beautiful You starring by fellow label-mates Choi Minho (from SHINee) and Sulli (from f(x)). She also sang “And One” for SBS’s drama ‘That Winter, The Wind Blows‘, which was released on 13 March 2013. The OST debuted #1 on the Billboard Korea K-pop Hot 100 chart. 
On May 7, 2010, she had her musical debut as the main female role in “Midnight Sun“, which is based on the Japanese novel “Taiyō no uta” by Aya Denkawa. The musical is about Kaoru Amane, a 17-year-old girl, who suffers from Xeroderma pigmentosum, which forbids her from going out during daytime. She keeps her hopes up by writing songs and singing every night at a train station. Taeyeon received good press for her performance. Furthermore, she learned to play guitar for her musical performance.
Taeyeon and her band mate Seohyun were cast as voice actors for the Korean dub of the 3D animation Despicable Me. Taeyeon dubbed the voice of the character Margo, while Seohyun’s role is Margo’s younger sister Edith.
She was featured on Munhwa Broadcasting Corporation reality-variety show We Got Married as part of the third rotation of couples; she was featured with comedian Jeong Hyeong-don. When this news was announced on January 7, 2009, it caused an uproar among South Korean netizens due to the 11-year age difference between the two.
On February 22, 2012, she was a MC for First Gaon Chart K-Pop Awards together with Joo Younghoon and also for 2012 Korean Music Wave in Bangkok which was held on April 7, 2012 together with Tiffany and Nichkhun. During the hosting of the “First Gaon Chart K-Pop Awards” show, Taeyeon encountered a toe injury. Taeyeon’s toe nail had been disconnected from her toe and she was unable to receive the award with her members.
Taeyeon became a DJ on MBC Radio‘s Good Friend Radio, which she co-hosted with Super Junior‘s Kangin until he left on April 19, 2009. She has received the nicknamed “DJ Taengoo”. Taeyeon ceased her DJ duties from April 26, 2010 onwards.
SM Entertainment revealed that Taeyeon, Tiffany and Seohyun will form a SNSD subunit called Taetiseo; they released their first mini-album Twinkle on 2 May 2012. The subunit has different musical direction and style concept from the nine-member SNSD.
Angel Price Music Festival
On April 17, 2011, during a performance at the Angel Price Music Festival, a male audience member trespassed onto stage and tried to pull leader Taeyeon off the stage. Member Sunny reacted the fastest out of all the rest of the members, and intervened. The male trespasser was subsequently stopped and apprehended by the host Oh Jung Tae and security staff. Taeyeon was later praised for her calm and professional attitude as she continued the performance until it ended. SM Entertainment later reported that everyone thought the trespasser was a staff member, and that the girls were fine and were resting as of the time of the statement. Social commerce business, Coupang, which handled the ticket sales at Angel Price’s request, released an apology to Girls’ Generation and fans for the incident, stating that “Coupang was inadequate in the way we sold and distributed the tickets.” Coupang took full responsibility for the incident and promised to give a full refund to those who bought tickets for that event. However, some netizens criticized Coupang in that the business expects a mere refund to be an acceptable apology to all, especially towards Taeyeon. Many were bitter in that something worse could’ve happened to Taeyeon, and that the concert failed to protect the artist that they invited.
On October 24, 2011, the website soshified.com organized a SNSD Fanmeet in New York City. Taeyeon performed the opening number (“The Boys”) but during the rest of the meeting was very subdued and pale. During the following MTV interview, she appeared distracted and bored, even resting her chin on her hands. Initially, her actions were attributed to the onset of a Common cold; it was later announced that she was suffering a peanut allergy reaction, and was experiencing anaphylaxis with shortness of breath.
