Is EVERY bit of the game in the phase files?

[StellaInTheSky]

I have searched high and low, far and wide for the potions minigame music...and it's non-existent in the phase files as far as I can tell. So this leads me to wonder...there are many, many, MANY things (audio clips, textures, maps, etc.) throughout the various phase file folders but is everything in these files? Why can't I find the potions game music when I can find all of the music from any other part of the game--including the holiday music which technically is only in the game for a short time?

I'm slightly irritated because I really love this music and have no means of recording it on my computer while in-game. I feel like I'm either missing it completely or it's simply not in any phase file folder...

So for my more techie pirate brethren, what say you? Is every part of our game in our mystical phase files?
