This song sounds like a remix to "eternal rest" SH1? The same drum is present throughout this song can be heard around 0:46 in the fore mentioned song title.
I just went through the ps2 files with the afs explorer and could not find this track. I could find End of small sanctuary and other stuff. Even the results screen song. But I couldn't find this track on the pc files or the ps2 files.
Only way to access it would be to stick the disc into an optical drive on a PC and browse the files. You'd probably have to use a special player/codec to get it to play, been a while since I've messed around with the files on the disc.
