Pink wanted to call this album Heartbreak Is a Motherfucker — a fitting title for a record that follows her divorce from pro motocross rider Carey Hart. With songwriter Max Martin chipping in, the rock diva finds ways to make emotional rawness go pop on Funhouse, turning out silly, catchy funk and supercharged electro. She drinks in the afternoon, forgets to eat and shows off her feisty side on the arena-ready hit “So What,” where she disses Hart and looks to start a fight. Still, Pink has shown more personality before, and some cuts, including the goopy ballad “I Don’t Believe You,” make her sound like just another big-voiced chart-buster. Funhouse would be more fun if Pink went easier on the bad-love songs.
