Katy Perry achieved maturation with Prism, the 2013 album anchored on the self-empowerment anthem "Roar" and the club smash "Dark Horse." Considering how "Roar" scored the closing stages of Hillary Clinton's 2016 campaign, it would've seemed like a logical move for Perry to build upon its adult alternative affirmation but she's instead chosen to use "Dark Horse" as a blueprint for Witness, the long-awaited 2017 successor to Prism. Perhaps Perry shifted her approach after "Rise," the "Roar"-alike written for the 2016 Olympics that she also performed at that year's Democratic National Convention, failed to crack the Top Ten, perhaps she always planned to construct this album with electronic beats and synths, but Witness is so slick with synths it seems slippery.
As an album title, Smile carries an air of determined pleasantry, and Katy Perry could use her share of good spirits in 2020. Witness, Smile's predecessor, found Perry pushing her artistic limits, an exercise that didn't find an audience, so she's chosen to retreat to safe territory for Smile. Mostly, this results in Perry devoting herself to dance-pop that's coolly glassy on the surface and vaguely positive underneath. It's dance music that's not intended for the club; rather, it's a soundtrack for everyday events, from work to exercise to relaxation. It's also music that tacitly acknowledges that Katy Perry is beginning her slow transition away from pop culture's center stage.
