Custom Soundtracks is something we have been looking into being able to add your own music and maybe even port the Driver 3 music into there.
Here You'll find some information about a possible music converter in development for the game.
At the moment it is possible to use the *78 music in *06 but it will take some time to convert them. I'm thinking I'll make a tool/program which simplifies the renaming process. But if you have some time and you want to port the music from *78 to *06 I'll show you how!

I'll create a topic just for showing you how to do this soon! But right now I'll tell you how to quickly do this!
Ok, first you'll need to locate your driver: parallel lines directory.
Then you'll need to open up the music directory.
Then you'll be presented with lots of XA files. You can see what these .xa files are by
Clicking here.
Form looking at the .xa files on that list choose the ones you like and the ones you'd like to replace.
The copy the music directory somewhere else on your computer as a backup!
Then delete all the songs you don't like. From this stage you can play the game and the game won't crash when a songs not there it'll just skip the song and go to the next song.
Then you can copy the music you like from the *78 range and copy them over to another folder from that folder you can rename it to one of the song file names you deleted and then you can move it back. You can do that for as many songs as you like.
and then you can load up the game and have those *78 songs in *06.
If you cannot really follow this quick tutorial I'll create a better one in the next couple of days in the experiments topic folder!
and i want to listen my songs but is there a way to do it? 
The link is broken! Ugghh! Now I might want to buy the XBOX version.
