“Can’t Stop,” in contrast, is adamantly positive and encouraging; the only thing Kiedis, a recovering substance abuser, says he’s addicted to is “the shindig.” From there, his words march through a looping chain melody occasionally interrupted by a chorus pearl: “The world I love, the tears I drop/ To be part of the wave, can’t stop/ Ever wonder if it’s all for you?”
