Basic Sound Manager For XNA GS 3.0

This is a basic sound manager for use with XNA Game Studio 3.0. It utilizes the SoundEffect class to play sounds as well as the Song class for loading and playing music. It even lets you search a Zune's MediaLibrary for a song by name in the case that such a content file can't be found.
