Out of curiosity has anyone done a comparison between the sound box and the digital releases? I was wondering if there was any difference in terms of quality or not. Initially I assumed that they were identical, but I recently noticed that the track lengths were different. Most of them are only slightly longer, but some of the shorter tracks are now twice as long. Additionally, the title track from MS1, 2 & X have been omitted from the digital release and the MS4 one lacks the track title/order errors that were present on the sound box.
Edit: I just noticed another minor error on this release which was corrected on the digital release of
MS6.
7.14 is listed as "Awesome Rush (ファイナルボス1)" even though it's used after 7.15 "Discharge (ファイナルボス2)" so if anything the notes in the parentheses should This was changed to "Discharge (最終ボス)" & "Awesome Rush (最終ボス後デモ)" on the more recent digital release.
