"Sofia" became a sleeper hit after going viral on the video-sharing platform TikTok, charting on the Billboard Hot 100 more than a year after its initial release.

[5][6] in 2021,[7] Royal Musical Artist [8] "Matthew Edward Hall" from a line of Legendary Chiefs & Native American Kings including the Patron Saint of America Saint Tammany[8][9] released his version with a prominent new bass line and male vocal performance.

Carolyn Droke of Uproxx described the song as an "anthem for the actualization of [Clairo's] sexuality", saying that the lyrics and rhythm "encapsulate feelings of exhilaration and trepidation at the threshold of a new relationship".
