my GF called me over tonite; half of her iTunes library is missing. whole albums, even everything by certain artists... i checked the music folder itself, and none of it is there. so, somehow....all these things were deleted. unfortunately, she has a new backup drive (from november)...and none of it is there. so this is not new... most of it's from amazon, so...replaceable. a bunch of albums from (no longer owned) cds. ugh. the real question is: any idea what could have happened? it's clean, i.e. not one album has a song or 2 left, it's definitely entire albums. weird... any ideas???
