I understand the objections people have to this album. It is somewhat conventional, and it perhaps lacks the lyrical deepness of earlier work (it is certainly the antithesis of the album that preceded it, "The Nylon Curtain", which was Billy's deepest emotional work. Actually, one could make the argument that this is early Beatles to the Curtain's late Beatles influences). However, context here is everything. Billy wrote this album very quickly when he was falling madly in love. Each word, each note is as deleriously happy as a Shakespeare comedy. If you have ever been in love, you can appreciate this for what it is.
Melodically, this is inspired, transporting us back to a simpler time, and each song is reminiscent of a doo-wop street choir sitting on the steps in Brooklyn (as depicted on the back cover). Don't look for double-entendres, or analogy here. As Billy sings on "Keepin' The Faith", "gonna listen to my 45s / Ain't it wonderful to be alive / when the rock n roll plays". If you can listen to this album, without tapping your toes along with it, you must be dead.
