Here's the MU version for the people who call Rapidshare "Rapidshit":

It's an incredibly strong OST with only a couple of bad tracks. "Orange Kandera" is the only real "skip at all costs" track and that isn't even Hitomi Kuroishi's fault. The two "comedy" tracks that follow aren't that great either, though "Eien no Toshi" has plenty of cowbell for those who always demand more cowbell.
Everything else is golden, and pretty much every essential track from the series makes it in including the "adventure" version of the Metal Age theme. Kuroishi even graces us with a piano solo near the end amongst her Nakagawa-esque orchestration. The ethnic percussion element, though, has faded drastically, and electronica is slightly more prominent than on the 1st OST.
There are plenty of standout tracks, I can't possibly list them all. Everything that is needed, from menace to emptiness to warmth to horror to sadness, is here in spades. Near the end a melancholic determination sets in, lending a ton of power to her orchestrations, nicely supplemented by her electronics. You will soon realize that the apprentice has eclipsed her master. Kuroishi will hopefully find plenty of work over the years to come, and continue to flesh out her own voice and style, giving us something equal to Kotaro Nakagawa in scope but different in execution, and something more in heart.
