Opened iTunes this morning and it started doing some kind of update or review of files. I stopped it, which was apparently a mistake. Now about 400 songs are missing from the application, though as far as I can tell, they all seem to be in the iTunes Library. So I can put the songs back on iTunes.

More irritating is that all the playlists that were on the application are missing. Any way to restore them? Are they stored in some folder that I'm not finding?
