In 1985 was traveling from Malaysia back to the states with a stop in Hong Kong. I bought a Sony D-5 CD player there because I knew that was the future In a Hong Kong record shop I bought the Star Wars 2-cd set and Raider of the Lost Ark single CD.
The next stop Hawaii where I saw Cocoon. I got Cocoon there in part because it was the first soundtrack listed in the end credits as being avail on LP, tape, and CD.
I still have all three of those albums on my shelf, but they have been superceded by expanded versions, sometimes twice over.
Young HORNER orchestral soundtracks were perfect for the new CD medium in the 80s.
In December 1987 I bought AN AMERICAN TAIL, my very first CD ever, any music genre. Few months later I took GORKY PARK and eventually WILLOW (in Amsterdam Boudisque record shop, I wonder if it still exists).
