Ok, I get it, the OST is iconic (and over-played). But if you want something similar to that sound, listen to Analog Sweden's Moments Lost - a hommage to the OST. Good for evoking the setting, without being tied to scenes in the movie(s)!

Of course, the old PC game soundtrack as well is a mighty fine addition: https://www.frankklepacki.com/ost/vg/bladerunner
Anything related and similar sounds out there?
