“What’s Up?” is a song by American rock group 4 Non Blondes from their 1992 debut album, Bigger, Better, Faster, More!. It was released as the album’s second single in 1993. It was successful in the United States and in several European countries, peaking at number one in Austria, Belgium, Bulgaria, Germany, Ireland, the Netherlands, Norway, Poland, Sweden, and Switzerland.
The title does not appear in the song’s lyrics. However, the phrase “what’s going on?” is prominently included in the chorus. The title was chosen to avoid confusion with Marvin Gaye’s 1971 song “What’s Going On”. Linda Perry told Rolling Stone that she hated the song’s production. Perry revealed on Behind the Music that she hated David Tickle’s reworked version (with different lyrics) intended to be used for their album. She had told this to Jimmy Iovine, who agreed, preferring Perry’s demo version over Tickle’s. Tickle’s instrumental (over the original vocals) could be heard on Perry’s episode of Behind the Music; Tickle’s version was never released. The final version was recorded in one day after Iovine allowed 4 Non Blondes to re-record Perry’s demo version. The music video was directed by Morgan Lawley.
“What’s Up?” ranks number 94 on VH1’s 100 Greatest One-Hit Wonders, and ranks 86 on the MuchMore The Top 100 One Hit Wonders.
The recording received considerable airplay success. It reached number 14 on the US Billboard Hot 100 and went gold, but peaked higher in many other countries, reaching number one in Germany and Ireland, while reaching number two in the United Kingdom and Australia.
However, Gawker journalist Brian Moylan included the track in an unranked list of the “10 Party Songs We Never Ever Want to Hear Again”.
