 Many reviewers focused on the album 's light lyrical themes . Entertainment Weekly called the references to Stefani 's clothing line " shameless " and stated that " each song becomes akin to a pricey retro fashion blurb " , and Pitchfork Media quipped that " the Joker 's free @-@ money parade through Gotham City was a much more entertaining display of wealth , and he had Prince , not just Wendy & Lisa . " Sal Cinquemani of Slant Magazine commented that the album 's " fashion fetish [ ... ] gives the album a sense of thematic cohesiveness " but that the " obsession with Harajuku girls borders on maniacal " . The Guardian disagreed with this perspective , arguing that " her affinity with Japanese pop culture [ ... ] yields a synthetic sheen [ ... ] that works well with the other point of reference , hip @-@ hop .
