Perhaps I am doing something wrong, but when I set up a custom submenu under music, the same submenu item shows under movies also. Or if I create one under movies it shows up under music also.

u need to use a different subemnu for each option ( one or how many you want for music, one.. for movies etc )

I didn't follow, but what I did was create a playlist for music and set it as a submenu under music, but it also shows as a submenu under movies. I don't really want a music submenu item showing under movies.
