This contains the file that you need to put into the original game directory. Please read the readme and the instructions before installing it for the first time.
1. Open Mafia's game directory. Here is the easiest way:
Open Steam Library < Mafia < right-click Mafia < Manage < Browse Local Files.
This should open the Steam folder of Mafia. For those who don't have Steam, you may have to use Open File Location.
2. There should be a folder called "sounds." If you don't have that folder, simply make a new one called "sounds." Without quotations and all in lowercase.
3. Go inside your sounds folder. Since your folder is quite new, you need to create a music folder to host your custom content.
If you don't have a music folder yet, create a new folder that says "MUSIC." All in uppercase, and without quotations.
4. After creating your new music folder, come back to this mod's folders, and then grab the .ogg files to put them in Mafia's directory.
They should be in .OGG format as this is what the original game uses to play music.
5. Load the game up and enjoy. :)
