Every single link I've found for this so far has been dead (not too easy to search for a name with 'threads' in it either). Can I ask if anyone has a 320 KBPS CBR or FLAC copy of the OST?

Seconding~. (MP3 preferred for me.)

To ease the burden of supplying it: if someone can supply an FLAC copy, I'll convert it to 320 kbps CBR MP3 format and re-upload it. And then we can have both copies floating around the forums.

for great bumpage
