It's amazing that Microsoft hasn't fixed this. It's a bug that they seemed to have ignored. I found the fix on a different site and it's relatively simple, but you must edit the registry as follows:
1. Start regedit.exe
2. Navigate to
"Computer\HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\TunerConfig"
3. Look for setting PREFERREDMETADATAPROVIDER -- it should have a value of "pmpMusicMatch"
4. Edit the setting PREFERREDMETADATAPROVIDER, and clear the value so you have a blank value
5. Save / exit regedit.exe
6. Restart Windows Media Player, you should be restored back to fai.music.metaservices.microsoft.com
I hope this helps.
