Hi guys,
This is one of my favourite games ever. I actually own full-blown original with Plasma Pack and Cryptic Passage add-ons (yea, I'm a Blood freak).
I did not read all the pages of this thread (gave up around tenth), so I dunno if someone mentioned it here before or not, but probably not. So...
There is a dude, Mark McWane, who actually made remix of Blood music. But it is not some simple synthetiser remix, but really good job that enhances the music, but does not take away the ambiance. Highly recommended!

Good luck!
