my itunes crashed!

something happened to itunes just now. i was listening to a song and then it just stopped playing and hung. so i restarted my powerbook and after that when i opened itunes, it said - importing xml library file or something. i wasn't sure why it was doing that and i stopped that in the middle. then when i looked at my library it had only like 300-400 songs. all the rest weren't in the library. at least all the songs were still there in the itunes library folder. so i had to add all the the songs from the itunes library to get back my original full library with intact genres. but in all this i lost all the playcounts, all my old playlists - smart as well as normal ones, the playlist of all my favorite songs, playlist of recently added songs, all the playlists of the most played songs, even lost all my groupings. :(
but then luckily i found a xml life of my library i had saved about a month ago. so at least that had all the groupings, and some playlists. so all wasn't lost. i was mainly happy that i regained atleast the one playlist which had all my favorite songs, but also sad that i lost all my playcounts. so in a way my library is brand new, like a blank slate - with no trace of what all i heard before and how many times i heard it. one day i'll even have to part with all my songs - i know its inevitable...
