Are you playing the game on a Mac or Windows laptop/desktop? If so, look in your application files under the game's folder for a 'sounds' folder. You'll find the tracks there. IIRC they are in .ogg format, which only a few music players can handle. I suggest searching the web to find suitable software for your computer.

If you play on an iOS or Android device I can't help, as their files aren't accessible in the same way.
