“Ur So Gay,” the breakout pop single by this former gospel prodigy, has been getting some big gay hype online because it perfectly captures the hipster zeitgeist of 2008 Los Angeles — a trendy indie-rock mind-set with no discernible message, just a bleating electroclash soundtrack and a closet full of fey neon pants. When Perry wittily eviscerates an ex-boyfriend (“You’re so gay and you don’t even like boys”) over a brassy, hiccupping beat, it’s momentarily novel, but soon the song wears as thin as her man. The rest of the album plods with formulaic, hormone-heavy Kelly Clarkson outtakes, or perhaps Liz Phair during her bleak, sparkly descent. Exile in Gayville it ain’t.
