Question about Blade Runner soundtrack?

I have the old 8 track CD and just noticed there's a newer 12 track version.
However the new one is missing 2 tracks from the original:
Farewell and End Title Reprise.
But it has some new songs I haven't heard before.
So, do you think I should buy the new version with12 tracks or just keep listening to my old and much loved CD?

Perhaps you should look into the 'Esper Edition' with 33 tracks

Unfortunately, it's not licensed for public sale.

Here are a wide variety of other options (WOW!) --
