iOS5 Removed All the Content from My Playlists

[Built]

When I updated my iPad 2 to iOS5 last week, all of the content of my playlists disappeared. The playlists are still there, but there is no content in them.

Has anybody else experienced the same? When I restored my new iPad 3 from a backup of the 2, the same thing happened (of course).
