Not the End of the World

Katy Perry's Smile album came from the pop star overcoming a tough couple of years after her previous record, Witness. She experienced depression because of its lukewarm performance and problems in her personal life before finding her smile again. This trap-flecked song, released as the album's third single, finds Perry detailing the life lesson she's learned: Failure is ultimately subjective. You might see a cliff, but I see a way to fly Flipping off the flop, now I just enjoy the ride After two-and-a-half nightmare years, Perry no longer cares how her music performs: If a record flops it's not the end of the world. She told People she'd been able to refocus her priorities thanks to a combination of medication, therapy and family support. "It got me out of this desperate loop of being the best pop star ever," Perry explained. "I just really want to be a human being and have the dimension of life... I get to live life, and I get to bring life into the world. Finding the gratitude in this pain has been a real journey, but the outcome is worth it."

During the pre-chorus, Perry interpolates Steam's 1969 taunting and playful song "Na Na Hey Hey Kiss Him Goodbye." Na, na, na, na What a time Na, na, na, na To be alive Don't say goodbye The Steam song is frequently played at sports stadiums when the home team is about to win or an opposing player is ejected from the game.

Katy Perry and singer/actress Zooey Deschanel have often been mistaken for one another by fans. The California singer enlisted her celebrity doppelganger to fill in for her in the video, as it was filmed right after Perry gave birth. Female directing duo Similar But Different (The Chainsmokers, Liam Payne) shot the clip, which shows some aliens mistaking Deschanel for their favorite pop star and abducting her. She is tasked with performing a concert for the aliens as Perry in order to save Planet Earth from self-destruction.
