by Stephen Thomas ErlewineBased on their infectious summer single "Walking on the Sun," it was easy to dismiss Smash Mouth as a one-hit wonder, since it was hard to believe that they'd be able to top that sun-kissed delight that was easily the highlight of their debut, Fush Yu Mang. Perhaps that's why their second record, Astro Lounge, feels like such a surprise, since it carries through on the promise of "Walking on the Sun." Like Sugar Ray -- a fellow veteran of the ska-punk underworld who delivered a follow-up that owed more to melodic pop and new wave than its hit predecessor -- Smash Mouth have created an album that is unabashedly fun, catchy, and lightweight, the ideal music for a car radio or a day at the beach. It's true that nothing on Astro Lounge is as immediately grabbing as "Walking on the Sun," but every song shares the same party-ready mentality and irresistible, trashy AM-radio vibe. No, nothing on Astro Lounge is particularly deep, but it's all good fun and it never disappoints -- which is quite a remarkable feat, since one-hit wonders rarely deliver a second album that betters their first.
