Missing Tracks

[Steksis59]

I have a number of pop psych playlists all the tracks from the rubbble collection cd's are no longer available any ideas why?

They are still listed under albums but all the tracks are greyed out.

thanks

I am also interested in this problem. An entire album from one of the artists I listen to just up and disappeared. All other albums are still there though. What gives?
