Ubuntu :: Hiding Folders Inside Of Shared Folders?

I am setting up a lubuntu nas with all of my music, movies, etc on it. I want to give my kids access to my mp3 directory, so I can move all of the kid appropiate music into the root of my mp3 dir, in the same order I have all of my music sorted. Under the Music folder, I have them sorted, in folders, by letter. So A, B, C, D, etc... Now, in those folders are the respective artists. So where there may be something approipate in the P folder (say, Paramore), there is something inapproipate (say, Pantera)Now, when the kids go to the P folder, I don't want them to even see the Pantera folder. I just want them to see the Paramore folder. I tried a test using chmod 711 and chmod 700 on a directory with a test user, and the user can't access the directory, but can still see it
