at the bottom of the site someone posted mafia 2 audio extractor. click it and save it.

now go to your mafia 2 file directory. to copy the music files wich are FSB format.

they should be in the steam folder find your STEAM folder in C or whatever disk you have it on.

ones in the STEAM folder go to STEAMAPPS

than go to COMMON there you should see Mafia ii public demo, open it.

in this flder click on PC than on SDS and then look for a folder called MUSIC

ones in the folder "MUSIC" click RADIO than click 50, you will see the four radio stations.

now go to my music (somewhere in windows) make a folder called mafia 2 music or so XD and COPY the songs from the radio stations.

now the extractor comes in handy.
open the extractor using WinRAR
in the extractor click OPEN and than slecet your mafia 2 songs folder you just made and where you just coppied the songs to.
select all the songs you like or just some,:P
in the extractor click on SAVE or SAVE ALL and you are done they are now converted to WAVE SOUND so Itunes and windows media player are abled to play them.

the coppied files wich are still in FBS can be deleted

DONT DELETE ANYTHING IN YOUR GAME DIRECTORY ONLY IN YOUR MY MUSIC FOLDER.
