i booted up my mac this arvo, clicked on itunes and the following message came up:
"the itunes music library file cannot be read because it does not appear to be a valid library file."

It means the library file that keeps track of all your music, playlists, preferences, etc. has become corrupted and is no longer readable. The music files are still there in your home folder ~/Music/iTunes/iTunes Music and can be re-imported into iTunes.

However, unless you have a backup of the iTunes Music Library file, I do not know of any way of recovering it.
