this is done a little differently from the other sonic tracks from the project. in this file, not only is the stage theme present, but the megadrive synth pre-boss track as well. the stage has a similar feel to the sky sanctuary stage from S&K, but the design is still much different, hence the move from what could have been a very upbeat track to one of mixed ups and downs. the style starts as one of those "finally, some different scenery" stages, but it's also atop a massive (MASSIVE) flying warmachine that's starting about to fall out of the sky. this is the second-to-last zone in the chapter.
the second half of the track is done in a genesis/megadrive style (as all boss acts do) and acts as a lead-in track to the actual fight, in this case being only a chase out of the cruiser before it plummets into the ocean.
i won't put the chase theme on here, more than likely. no real reason to.
EDIT: totally forgot i never uploaded the better version, so that'll be up sometime
