Lovely was released in 2018 as a single by American singer Billie Eilish and American singer Khalid, written with Finneas O'Connell for the soundtrack to the second season of the Netflix series 13 Reasons Why. The slow, piano led ballad became one of Eilish's most streamed songs and a staple for fan edits online. Short excerpts of its chorus and intro circulate widely on TikTok and in video edits, where the instantly recognisable vocal is used as shorthand for grief, heartbreak and quiet emotional moments.
