I am a fan of the movie, but never really gave much thought to the score until recently. It seems highly regarded considering how many different versions of it exist. Now,... I guess i am asking for recommendations as to what version is the best and why?

ANy help?

I'd ask that in this thread: The Blade Runner Soundtracks Ultimate Thread (Thread 72496)
In it there are numerous versions, someone there will be able to answer properly ;)
