During her career beginnings, Taeyeon established herself as one of the most renowned vocalists in South Korea with soundtrack recordings for Korean dramas, notably "If" for Hong Gil Dong (2008) and "Can You Hear Me" for Beethoven Virus (2008); the latter helped Taeyeon win the Popularity Award at the 2008 Golden Disk Awards. Referred to as the " Queen", she further recorded popular soundtrack hits including "I Love You" for Athena: Goddess of War (2010), "Missing You like Crazy" for The King 2 Hearts (2012), "Closer" for To the Beautiful You (2012), and "And One" for That Winter, the Wind Blows (2013).

Her debut extended play I (2015) peaked at number two on South Korea's Gaon Album Chart and has sold over 160,000 physical copies. The title track peaked atop the Gaon Digital Chart and has sold over 2.5 million digital units. In February 2016, Taeyeon released "Rain" as the opening single for digital music project SM Station. The single reached number one in South Korea and has sold over 2.5 million copies. Her second EP Why (2016), reached number one in South Korea and spawned two Gaon top-ten singles–"Starlight" and "Why". Taeyeon's first studio album, My Voice (2017), peaked atop the Gaon Album Chart and has sold over 230,000 copies in South Korea. The album features three South Korean top-five singles: the chart-topper "Fine", "11:11", and "Make Me Love You".

Taeyeon further released two South Korean top-five EPs, This Christmas: Winter Is Coming (2017) and Something New (2018), and a Japanese top-ten EP, Voice (2019). Her second studio album, Purpose (2019), debuted at number two in South Korea with first-week sales of 154,000 copies.
