What Is Not to Love

As it turns out, the smug title of Imperial Teen's second album, ''What Is Not to Love,'' is pretty apt. There's something fundamentally warm and cuddly about the mixed-gender quartet's seductive mix of indie-rock clichés (distorted guitars, diffident vocals) and hook-and-harmony-informed popcraft. Although the two arty seven-minute-plus tracks prove they should keep their songs half that length, those are the only missteps on this spunky, relentlessly tuneful disc.
