Blade Runner soundtrack?
 

The music during the ending of Blade Runner....not "Tears in Rain", but the track that logically should come before that... id it on the soundtrack? If yes, what is its title?

I already looked it up there....

The order of the tracks doesn't help me, as Tears in rain should come BEFORE the end credits music.

Actually the track listing does help. The track over the credits is aptly titled "Blade Runner - End Titles". It's track 11, and is a good little piece of music.

When what is that music called?

I'd have to check, but chances are that that piece of music isn't on the soundtrack album, there is a lot of music that isn't on the soundtrack album
