So what

The harmony of 'So What' is elegantly simple yet emotionally effective. It uses just four chords recontextualized between F-sharp minor (verses) and its relative major A (chorus). This pivot — the same chords, different tonal center — is the engine of the song's emotional arc: brooding defiance in the verses erupts into triumphant, anthemic release in the chorus. It's a textbook Max Martin move, making complex emotional shifts feel effortless to sing along with.

Pink wrote 'So What' with Max Martin and Shellback during sessions in Stockholm, channeling the raw emotions from her recent separation from husband Carey Hart. The songwriting captured a brash, unapologetic attitude toward the breakup, turning personal pain into a defiant party anthem. After reuniting with Hart in early 2009, Pink told Ellen DeGeneres she found it amusing to perform the song with him in the audience, especially the line 'You're a tool.'

Released as the lead single from Pink's fifth album Funhouse (2008), 'So What' is a post-breakup battle cry built on a martial beat and punchy synths. Written with hitmaking duo Max Martin and Shellback, the song rode its brash, unapologetic energy to number one on the Billboard Hot 100 and became one of the defining pop anthems of the late 2000s.
