Hello alesssiat,
Thank you for using Apple Support Communities!
It sounds like iTunes may have lost track of CD1 sometime after you imported it.
I would recommend recreating the iTunes Library altogether:
iTunes: How to re-create your iTunes library and playlists
http://support.apple.com/kb/HT1451
1. Quit iTunes.
2. Locate your iTunes folder (this is the folder that contains the iTunes Library and iTunes Library.xml files).
Operating System |
Default location of iTunes Folder |
Mac OS X |
/Users/[your username]/Music
|
Microsoft Windows XP |
\Documents and Settings\[your username]\My Documents\My Music\
|
Microsoft Windows Vista |
\Users\[your username]\Music\
|
Microsoft Windows 7 |
\Users\[your username]\My Music\
|
3. Open your iTunes folder.
4. Drag the "iTunes Library.xml" or "iTunes Music Library.xml" file to the Desktop. If neither is available, learn how to add files back to the Library (because the XML file is not available, playlists and other information will not be available).
5. Drag the following file from your iTunes folder to the Trash:
Mac OS X |
"iTunes Library" or "iTunes Library.itl" |
Microsoft Windows |
"iTunes Library.itl" |
6. Open iTunes.
Important: Do not add any content into iTunes at this point (such as by purchasing something from the iTunes Store).
7. Choose File > Library > Import Playlist.
8. Navigate to the "iTunes Library.xml" file on the Desktop.
- Mac users: Click Choose.
- Windows users: Click Open.
If your Podcasts list in iTunes is empty after following these steps, learn how to add them back into iTunes.
Allow iTunes to Scan for Media when you open it up for the first time after step 6.
All the best,
Sterling
