I have some John Williams soundtracks on Vinyl.
Return of the Jedi RSO for instance sounds so much better than the 1997 special edition CD they applied harsh noise reduction to.
My collection is far from complete however, i need the indiana jones trilogy, superman, and would also like to collect the scores for star trek 1-6 on LP.
Star Trek VI came out only on a foreign release LP and is scarce, i would like to get it without paying a king's ransom.
There are some modern soundtracks i think would be great on LP, but don't exist like Howard Shore's Lord of the Rings, or The Scores for Batman Begins and the Dark Knight.
