Columbia Reg 1 DVD features new music?

It sure does. The Sony region 1 disc seems to have some of the music replaced, most noticably at the beginning when Ko Fei goes to save Sam'a ass from the Thai gangsters. The original Thai song playing in the background was replaced with an English rock song on the Cantonese track and if you switch it to the English dub it restores the Thai song that is supposed to be playing in the background. Strange.
