Itunes corrupting it's library

[Frank Flynn]

Hi All,

Upon occasion (rare occasion but more than twice so far) my Mac has crashed
or frozen while iTunes was running.  Probably this was unrelated to iTunes
but when I restart iTunes has corrupted it's library - it will not launch
saying "This is not a valid Library..."

Trashing the Library will allow iTunes to launch but then I'll have to
re-import all of the songs and  create my play lists all over again.  I have
many songs and  playlists and this can take several hours.

My questions are:
-Is there any way to recover a corrupt playlist?

-Is there a way to prevent it in the first place?  I could make a back up of
it every time I change my library (yuck) it' about 5Mb.

Thanks,
Frank
