At a time in America's history when atheists and Christians wage a culture war, leave it to Brian Wilson and The Beach Boys to call a truce with an album titled That's Why God Made the Radio. An ode to the spiritual joys of pop music, it's the group's most enjoyable since 1977's Love You. Then again, the competition (Summer In Paradise? M.I.U. Album?) isn't stiff. The best tunes, the title track and "Shelter" among them, feel like variations on The Raspberries' 1974 chestnut "Overnight Sensation (Hit Record)," itself an amalgam of the best moments of The Beach Boys' 1965 masterpiece Today!
