Songs and videos gone, but they are on my Zune?

[becauseitis]

I have had my zune for over a year now. It had several songs and some small videos on it. All of the sudden though my movies are gone and my songs were not displaying in the menu. Somehow by navigating around, my music is showing in the menu, but the songs are scattered and are not organized by the Artist, like they use to be? And the videos I uploaded are nowhere to be found. Only the default ones that came with my Zune. Does anyone know what the problem might be?

That's... very strange. Have you tried resyncing everything after deleting it from your device?

If you delete everything off your zune, make sure your library on your comp is clean then try resyncing.
