Sunday Best was released by American duo Surfaces in 2019 and found a much larger audience in 2020 when its chorus spread widely on TikTok. Built around a simple feel-good message and a laid-back pop sound, the track became linked to positive daily-life videos rather than a single dance or challenge. That broad use helped it move beyond the app into charts and playlists internationally. It remains a go-to clip because the hook is instantly recognisable, family-friendly and works without needing any context from the full song.
