"So What" is a song recorded by American recording artist Pink for her fifth studio album, Funhouse (2008). The song was written by Pink, Max Martin and Shellback while production was handled by Martin. Selected as the album's debut single, "So What" was first released to mainstream radios on August 25, 2008, through LaFace and Jive Records. The song incorporates musical styles of pop rock while consisting of a martial beat and synth backing. The lyrics are based on her separation from motocross racer Carey Hart, which occurred six months prior to the release. "So What" received generally positive reviews from contemporary music critics; many praised it for its aggressive and empowering nature while others deemed it childish and bratty. The song was also successful commercially, topping the charts in several countries across Europe and Oceania and peaking within the top five worldwide. In the United States, the song reached number one on the Billboard Hot 100, becoming her first number one hit on the chart as a solo artist and her second overall. "So What" also became her highest selling single in the United States, with sales of over four million downloads. The music video for "So What" was directed by longtime collaborator Dave Meyers. It shows Pink drinking while riding a lawnmower, sawing down a tree, streaking on a red carpet appearance and other activities. The video also features a cameo appearance from Hart. Pink performed "So What" on MTV Europe Music Awards 2008 on November 6, 2008. The song was nominated for several awards, eventually winning the MTV Europe Music Award for the Most Addictive Track.
