Sharing iTunes Library with two users on the same computer

Question

I have all of my music stored on a external hard drive.
Both users on the same computer have the iTunes music location folder as the external hard drive. How do I see music added in one persons log-in? For example: I just purchased two albums under one log-in. The second log in can not see that music unless I manually add it.
Both Libraries point to the same file location.
I have over 40GB of music and I am looking for a way to manage my music files more effectively and I want to make sure that both log-ins have the same music.
I followed the instructions in article HT1203 from the apple support site.

The reason you are having this issue is because you have a shared library but private databases. What you have on the external drive is the collection of media files (library) that each account is set up to access as the source for media. What you have not done is set up a shared iTunes database, so each user accesses the same library differently.
When each user opens iTunes, iTunes access the database on their account (~/Music/iTunes/iTunes Library). Therefore, their settings, views, playlists, etc., are private. When they add songs to their library only their database file is updated to reflect those additions; simply having files in the music folder does not mean that iTunes will recognize them, hence the reason iTunes asked you if you want to move the file to the trash when you delete it from your library.
The confusion here is the double use of the term library. The contents of you music folder most definitely constitutes your media library, as it is the collection of your media files. What you see as your library in iTunes is not your library but, for the most part, the content stored in a database table maintained by iTunes in the iTunes Library file in your iTunes folder. iTunes does not access your actual media files unless it is absolutely necessary. The general assumption is that what is shown in your iTunes “library” will actually mirror what is in your music folder.
So the missing step in your setup would be to switch to the account that has the most current iTunes library—that is the one reflects the actual contents of your music folder as of now—and follow this procedure.
1. Quit iTunes.
2. Move the iTunes folder to the Shared folder (./Users/Shared).
3. Launch iTunes, but immediately hold the option key to invoke the Choose Library window.
4. Select the database (iTunes Library file) now located in the shared folder.
5. If you do not see your content, go to iTunes’ preferences and reset the location of the music folder to the external drive.
6. In the other accounts, re-launch iTunes and change the library according to steps 3 and 4.
Now all users will have access to the same iTunes database as well as the shared library. The downside of this is that each user will have full access privileges. If you have iTunes 8, then to avoid the disadvantages that come with this type of set up, see [this thread|http://forums.macworld.com/thread/105366?tstart=0] over at Macworld.
