Songs do not appear in the Windows Media Player library

I read this on another topic, try it.

Hi,

This problem occurs because the Windows Media Player library database has become corrupted. 

To resolve this problem, clear the Windows Media Player database. To do this, follow these steps:

1. Exit Windows Media Player.
2. Click Start, click Run, type %LOCALAPPDATA%\Microsoft\Media Player, and then click OK.
3. Select all the files in the folder, and then click Delete on the File menu.

      Note You do not have to delete the folders that are in this folder.

 4. Restart Windows Media Player.

Note Windows Media Player automatically rebuilds the database. 

If this does not resolve the problem, clear the Windows Media Player database cache files. To do this, follow these steps:

   1. Exit Windows Media Player.

   2. Click Start, click Run, type %LOCALAPPDATA%\Microsoft, and then click OK.

   3. Select the Media Player folder, and then click Delete on the File menu.

   4. Restart Windows Media Player.

I had same symptoms as cturner003 in a 64 bit Win 7 environment.  But the problem was entirely different from everythin I read up to Nov 2010.   As I started looking into the file properties under the details tab, I noticed that all of these files had file attributes 'R' and 'S' set.  Turns out that somehow all of my music got marked as 'Read Only' \ 'System' files when I restored them.  My fault I'm sure.  Tried all of the solutions up to the Nov 2010 entries to no avail.  Finally discovered the issue.  Once I changed the file attributes, all of the music started showing up in WMP.  Should have picked that up sooner.

For these files, I couldn't find any way to change the attributes except through the command prompt.

1.  Click Start, Click All Programs, ClickAccessories.  Thenright clickCommand Prompt and select 'Run as administrator'.

2.  Type Attrib /? to get familiar with the attributes command.

3.  My music is stored in the path c:\users\glym\music.  So I fixed the problem with the following command string:attrib -r -s c:\users\glym\music\*.* /s /d

4. Once the file attributes are cleaned up, make sure Media Player is closed.  ClickStart , ClickRun, Copy and paste in: %LOCALAPPDATA%\Microsoft, ClickOK
5. Delete the 'Media Player' folder completely.  That gets rid of the database and the cached entries.

6.  Restart Media Player . . .  Bingo!

Thanks Microsoft for several useful Knowldege Base articles that I plagiarized here.
