On July 9, 2019, YAMYAM Entertainment confirmed that Taeyeon would be among the singers to record the soundtrack for the drama series Hotel Del Luna.[3] This marked the first time Taeyeon released a soundtrack recording after three years, following "All with You" for Moon Lovers: Scarlet Heart Ryeo (2016).[4] The song, titled "그대라는 시" (literally "A Poem Titled You") in Korean and "All About You" in English,[1] was produced by Song Dong-woon, who had previously produced the soundtracks for hit dramas such as Descendants of the Sun and Goblin: The Lonely and Great God.[3] "All About You" was released on July 21, 2019, as a digital single by YAMYAM Entertainment, under license by Dreamus.[2][5]
"All About You" debuted atop the Gaon Digital Chart dated July 21–27, 2019.[6] It remained on the top spot for one further week[7] and ranked second on the Gaon Monthly Digital Chart for August 2019.[8] Overall, "All About You" spent nine weeks in the top ten.[9] It placed at number 31 on the year-end chart, ranking 55th in terms of sales and 32nd in terms of streaming.[10][11]
Lee Seung-mi of The Chosun Ilbo commented that the "delicate" piano melody and Taeyeon's "refined" vocals created a mysterious charm that complemented the themes of the drama.[12] Hwang Hye-jin from South Korean news portal Newsen commented that the commercial success of "All About You" brought back the "OST fever" that last happened in 2017 with the soundtrack of Goblin, particularly Ailee's "I Will Go to You Like the First Snow". Hwang also praised Taeyeon's emotional voice and the "exquisite" piano that gave the song a grieving atmosphere.[13]
