"Are the tracks for Dracula's final dialogue and the finale before the credits supposed to be repeat tracks? Or is it an error?"
To tell you the truth, I'm not sure anymore. On my phone the game doesn't have any sound. On the emulator, the game has sound but it tends to disappear sometimes. I played and beat the game over 8 times and the Dracula defeat dialogue and ending did not contain any music. Then in another playthrough they did contain that repeated music. I played it yesterday again and I didn't get any music, however, if I went into the menu and out again, the music was heard.
So I really don't know if that's a bug in the emu or not. Until someone can confirm it on a real phone, I'll never be sure.
"At any rate, is there a chance you could list those original track names for us? Strictly for the sake of those forum members who can't download the game rips of course, or perhaps those of us who don't feel like downloading the full soundtrack for a third time."
Sure Mobius, here are the songs as they appear on the game with their official name included.
01 Resting Again (story introduction)
02 Title (title screen)
03 Order of Shadows (stage 1 intermission)
04 Daring Assault (stage 1 the mansion)
05 The Encounter (boss theme)
06 stage clear
