No, not the great Swedish band but actual soundtracks. We all have our own individual soundtracks for our lives but what of those that were made for stage and screen? The world has changed since the days of Rodgers and Hammerstein and Webber and Rice and what constitutes a soundtrack for today’s generation is a long way away from “Oklahoma!” or “West Side Story”. For every horrible cash-grab “Glee” volume there is a Trent Reznor-Atticus Ross collaboration on the score for “The Girl With The Dragon Tattoo” or “The Social Network” to balance the equation. Of course both of those were ‘scores’ which is a somewhat different kettle of fish.
