Google Play Music All Access Question

From time to time on music streaming services, albums or songs will be removed due to licensing agreement changes.

On Spotify and Rdio, I can see when this happens because songs will be grayed-out and unplayable in my playlists. I like this because then I know what songs I'm missing and can then obtain them elsewhere.

My question is... Does GPM All Access "gray out" songs that are removed from the service, or does it just silently remove them from your playlists?
