SAD! was released in March 2018 by American rapper XXXTentacion, born Jahseh Onfroy, as the lead single from his second studio album ?. Built around a guitar sample and emo rap styling, it became his biggest hit and reached number one on the Billboard Hot 100 after his death in June 2018. The track's short melodic loop and confessional tone made excerpts easy to reuse online, where clips circulate in edits, tributes, and reaction videos long after the chart run.
