In a reply to a Twitter comment to the official Panzer Dragoon Voyage Record account, Wildman has confirmed that there are no arrangements or new background music planned for the game "at this time".
Twitter user RareAlone asked a question:
@PanzerDragoonVR Question: Do you think it’d be possible to add the arranged BGM by from @ForeverEntert‘s @PanzerDragoonRE, arranged by Saori Kobayashi of @BraveWaveMusic, for your game? I genuinely enjoy the rearranged tracks more than the originals by the late Yoshitaka Azuma.
To which Wildman replied:
No arrangements or new BGM are planned at this time.
So, based on this comment, it does seem that Panzer Dragoon Voyage Record will use music from the original Saturn games. Wildman previously said that he wants to make a safe game which values the original, and using the original tracks would be consistent with this. However, it doesn’t rule out the possibly that the full soundtrack has yet to be decided at this point.
