iTunes amnesia
iTunes seems to randomly forget songs' locations. Every once in a while, a song will get a exclamation mark next to it and I have to locate it - of course it's right where it always was.
I've got no idea why, when or how this happens. There doesn't seem to be a pattern. The thing is I've never moved songs manually since iTunes 3 started organizing them for me (what a great feature!). Any suggestions?
