XNA creating an in-game file browser for music files

Question

so I'm currently working on a music based game. Much like audio surf, the user selects their audio file and then the game continues to process the level according to the music. Currently I'm using the FileDialog to select file, but this only works in window mode. What would be the easiest way to implement similar functionality with my game even when the game is in full screen. I want to implement something similar to Audio surf, where selecting a folder simply opens the location up.

Edit screenshot and how audio file browser works:

Before the user can start the game, an audio file must be selected. When the game starts, it simply displays the default directory. The user can traverse directories by clicking on the folder and can go back by clicking the back button. It will display only audio files if they exist in a folder.

Answer 1

I was able to implement this functionality using Neoforce GUI library available for XNA.
