When I read that blog, I assumed the music would be just rearrangements (like those standard 360 ports), but it's actually a total replacement of what I think was well scored, and I guess it's a good change for Namiki's earlier works, or more hardcore shooter music fans. Here is the playthrough videos of stage that may be subject to be deleted (
1,
2,
3,
4 and
5).
By the way, I found each stage had
a kind of official translation so I'll add this as the third tracklist (I expect deathsmiles will also have translated stage names as it's getting localized).
