I Kissed a Girl
Sal Cinquemani of Slant Magazine wrote, Perry's "lead single 'I Kissed a Girl' features a throbbing beat and an infectious, bi-curious hook, but its self-satisfied, in-your-face posturing rings phony in comparison to the expertly constructed ambiguities of 'Justify My Love' or practically anything in the first decade of Ani DiFranco's catalogue; it's like a tween version of DiFranco's tortured bisexual confession 'Light of Some Kind.'" Hiponline.com wrote that the song is "not nearly as interesting or exciting as you’d expect. It’s not even half as good as Jill Sobule’s song 'I Kissed a Girl'.” Glitterati Gossip agrees Sobule's song "was ten times better, because there was actual emotional content to her lyrics."
