So, since my personal hope of an OST included with the CE edition of part 2 were dashed upon the rocks of reality le sigh I was looking up finding my own copy but the seemingly most complete version is this:
I know the show wasn't as music heavy or centric as others, but were there really only 16 tracks in the entire show or am i missing something?
There are two OST CDs. The first is the one you found. I have it and it is well worth the money. The second was bundled exclusively with the first edition of the 4th DVD/BD in Japan, so if you can find it, it will probably be expensive. I'd suggest browsing Rakuten Global Market or other Japanese second hand stores for it.
Ah, k thanks for the help
