The iTunes Music Library file cannot be read because it does not appear to be a valid library file
AAAAAAIGH! I had been doing some advanced software installs (XDarwin) and did some royal system messing-with. Somehow, I managed to corrupt my iTunes. Terrible. Awful. I have 3376 mp3 files in my iTunes. Losing them would suck.
iTunes would simply not run.
But wait! Maybe there's a fix. But I couldn't find anything on the web.
XML Saved My Music
Here's what I did in my iTunes Folder:
I made a new folder: (Apple-Shift-N)
iTunes 3 Music Library
iTunes Music Library.xml
iTunes Music Library (2)
...to the new Backup folder
(( NOTE: SEVERAL RESPONSES I HAVE GOTTEN INDICATE REINSTALLING ITUNES IS *NOT* NECESSARY. Consider this step optional. If your recovery fails, reconsider adding it back))
Reinstall iTunes afresh <http://www.apple.com/itunes/>
Then do: File > Import...
Import your library back: Backup/iTunes Music Library.xml
If you have a lot of music, it will take some time But this solved my problem. I got my music and my playlists back.
Calyxa suggested I show the path to the files, and I did. Thanks Calyxa!
On 27 November 2003 Mike Conlen sent in this suggestion, for iTunes for Windows:
In Windows to do the same look under
My Documents -> My Music -> iTunes
Move the files iTunes Music Library.xml and iTunes 4 Music Library.itl to the Desktop
File -> Import
Change file type to XML and select the iTunes Music Library from your desktop
Wait while the files are imported.
