Dont know if anyone else has already written this, theres too many pagse to go through!
-But I think the zune software should have an option like itunes, where it keeps your music organised.. if you transfer music from a friend, or rip a disc with songs youre not sure about you have to manually move and change the names of each song.. (im a little OCD when it comes to that haha)
