"Hot Stuff" is a hit single released by American disco singer Donna Summer in 1979 as the first single release from her Bad Girls album through Casablanca Records. Up to that point, Summer had mainly been associated with disco songs but this song also showed significant rock influences including the guitar, which had never been used in a Donna Summer single before. In fact the very intricate solo was played by Ex Doobie Brother and Steely Dan guitarist Jeff "Skunk" Baxter. It was certified Platinum by the RIAA and remained at number one on the Billboard Hot 100 chart for three non-consecutive weeks. "Hot Stuff" would also win Summer the Grammy Award for Best Female Rock Vocal Performance, making her the first African-American artist to achieve that feat. It is ranked number 103 on the Rolling Stone magazine's list of "the 500 Greatest Songs of All Time".
The songs also lists at number 67 on Billboard's Greatest Songs of all time.
The song also topped the U.S. Hot Dance Club Play chart, with Summer's follow-up "Bad Girls" as a double A-side. The popular 12" single edition of the song plays the full 6:47 version of the song and then segues into "Bad Girls" 4:55 version.
