I have managed to copy all 27 tracks from the game. The way is simple but it's kinda boring.
If you are using a music program like Cool Edit Pro, you can choose from the "Properties" menu to "record what you hear".
Start recording a new file from the program and then load NFS Underground2 and simply let it play all the songs you want to record. It's like recording a tape in a deck, remember? The old times.
When you are done with that, exit the game and enter the program. Stop the recording process and begin splitting the tracks. You can then save them as *.mp3
I hope i helped you out dude,
See Ya
