So, are we just going to ignore the new music that was showcased in the video? Pretty exciting that they seem to have got it right.
Not sure about everybody else, but they're not exactly "new" tracks. To me, at least.
The first was one we've heard since the Kickstarter opened last year, as per Ziming's link. The second is a variation on the Shenhua's House (Day) theme ( https://www.youtube.com/watch?v=G-ftslnyJcQ&list=PL3BC9A1C95E5D2EF4&index=32 ), and the third is unused Shenmue II music BlueMue uncovered last year ( https://youtu.be/Pp6KnpKDD38?t=116 )
Actually it has been used in an Xbox-Shenmue Trailer
