Not sure if this is in the right category and frankly I really have no idea where to put it. Anyways, I've noticed several songs are missing. One of the songs from Nessus is missing (there are more than one per world) and the Hive music is missing, off the top of my head. I'm sure there's more as soundtracks always seem to do this for some reason. Maybe they're part of other songs but I feel like I definitely went through the whole two disc album several times and never heard them.
