Listen To Music Included With Game:

First, open your The Sims 2/TSData/Res/Sound directory. The names of radio stations, plus a few more including Build mode and Neighborhood music should be here in *.package files. Copy and paste the file corresponding to whatever you want to listen to into another folder. Rename it from [File].package to [File].mp3. You can now listen to the sound/songs included in the file.
