Hacking MY MUSIC folder leads to root directory !

[redsquash]

M3 DS REAL ver 2.8
I am running Moonshell
experience nil

The media icon leads me to 7 icons.
I select My Music icon.
this leads me to the root directory where I have all folders including those I named Music and games.

How do I get MyMusic to only have music files. MYMUSIC is a M3dsReal icon, not mine
nds folder has only games. It works fine

Also
I want the desktop image on the nintendo ds to be blank. At the moment there is a desktop image of Movie player...whatever the hell that is?
Reading music names or games names is frustrating because of the overlap of images
thanks
