My iTunes is not adding all my albums to my iTunes library

[TheAslan]

Hiya!!

Today i noticed odd problem with my iTunes, my iTunes didn't add all my albums to library?? I really don't know why, it adds some albums but not all...

My music is here:
G:\Music (where G:\ is external drive)

I tried so many times to add those missing albums to iTunes library but no luck...i tried add folder to library and add files to library but no luck...it will not appear to my iTunes library...

Here's how it looks in my external:
G:\Music\Delain\April Rain.mp3 (there's only 1 archive in every artist and then mp3)

Please help me!

iTunes version: 9.2.0.61 x64

1) Are all the affected files .mp3s
2) Have you tried moving any of these files into a different folder and re-adding
3) Do the files open up ok manually with iTunes??
