Blanked out whole album or select songs on it?`

[tgoedde]

Why do albums and/or select songs go grayed out and no longer playable? They appear on my list, but I can't play them.

Sometimes that can happen when a different version of the album in your library is made available and the one you saved is removed. Check the artist's page to see if that's not the case with yours.

Worst case it could be that the album was removed entirely due to licencing issues.
