On Enema of the State, blink-182 preserve their goofball pop-punk cred but acknowledge there's more to life than juvenile behavior. Sure, the lurching "What's My Age Again?" cheers on immaturity, and new drummer Travis Barker adds breakneck aggression to the band's chugging riffs. But blink's skepticism toward adulthood is more sophisticated ("Going Away to College"), and their anxiety about romantic relationships (both real and imagined) is palpable. The somber "Adam's Song," written from a suicidal person's perspective, is wrenching.
