Been a while since I finished Trauma Centre New Blood for the Wii and since I haven't posted about the soundtrack yet, I thought better late than never. All the tracks are mainly composed by Kenichi Tsuchiya who assisted Shoji Meguro for the DS game but, Atsushi Kitajoh was also responsible for a few of the tracks.
The one you'll find here is the unofficial version ripped by Cubed who also provided the soundtrack for Under The Knife and for Second Opinion. There's actually an official soundtrack available this time which also seems to coincidentally contain 39 tracks. Odd that I can't find it on Atlus Net.
