you didn\'t explain how to choose a music file and adding it:

Go to options and go under sounds->requests and click on the button near the bottom that should start with \"C:\\" and then select a folder that has music in it. then select the file type inside the droplist above the button. Then you go to Sounds and keep pressing the button untill a popup comes up that has music files in it and select the song you want from it. Then click OK and your set.
I hope it helps ^_^
