Lost iTunes Song

I just noticed that my itunes library had 1111 files this morning. I made a smart playlist of what i added today. It says i added 31 songs but now i have 1141 files. So, i must have deleted something today. Is there anyway of finding out what it was? Help...im confused.

Are you subscribed to any podcasts? Because that's the main thing, I can think of that would make your songs count change, becasue iTunes deletes and adds podcasts.

Yeah...but i have them automatically update onto my ipod. Thanks anyway...i guess i just deleted one of the songs i didnt add today without knowing it.
