I have all Pangya Mobile files (at least the very last update’s worth), and I could provide them, but it’s between 2 to 6 GB of assets that I first need to find a place for.
To fulfill your general request however, here’s a direct rip of all music files from the game assets. It’s in OGG because that’s what the game says they have been provided in, converting them to WAV wouldn’t do much aside of blowing up the file size.
