"?" received generally positive reviews from critics, and became XXXTentacion's first US number-one album, debuting at number one on the "Billboard" 200 with 131,000 album-equivalent units earned in its first week. The album has since been certified triple platinum by the Recording Industry Association of America (RIAA). It was supported by three singles: "Sad!", "Changes", and "Moonlight". Following XXXTentacion's death on June 18, 2018, "Sad!" topped the "Billboard" Hot 100, where XXXTentacion became the first act to earn a posthumous Hot 100 number-one single as a lead artist since The Notorious B.I.G. with "Mo Money Mo Problems" in 1997.
