I suggest you follow the link and download audacity: http://audacity.sourceforge.net/?lang=de
It's free and after the installation you choose the folder open file in the menue task (left) and open the wav -file "Game/Body"
Press the play button and listen. If there's a break between the songs you can also wind forward, because you can see the silence in the stream.
There you can split the track with opening the theme "project" in the task menue and choose add a ( I don't know the real words but it's the second theme from the ground up to the top in the menue). In the end there shows up a little red flag as a sign for the place of splitting the track.
Save project and copy multiple tracks to a folder you created before on your desktop. You can choose for wav again or mp3 for the multiples.
Sorry, but I'm at my office and can't look at audacity right now. You should check out the menues in the task line above before starting something quick. Actually the whole program is easy to handle.
