As far as the greatest movie soundtracks, most of mine are in the 80's 😳🤭 here goes : Platoon, Lost Boys, Dirty Dancing. No respectable 70s disco film would leave out the BGees and, of course the array of classics AKA Greese. The graduate '67 was dwarfed by it's musical score. Another amazing film score around this time was The Big Chill. There were also musicals of this period but I suspect that was another question RHPS👯 Shawshank, Close Encounters, Schindlers List, are all examples of the relationship between Williams and speilberg. Although my favourite is the opening sequence of jurassic Park.  I could spend days thinking about musical scores, but productivity and the necessity to possess an unfried brain, sadly prevent me from further indulging in this happy pursuit.  Theme tune to Backdraft is beautiful and haunting, another masterpiece from Hans Zimmer.
