The problem is that I have about 100 GB of music and Explorer won't display them unless I sort by folder. I like your setup, it's what I'm trying to accomplish.
Winamp is my main music player and I use TagScanner to tag everything. Each mp3 of mine is tagged the same way.
Question: If you browsr the file using Windows Explorer (directly on the drive, not the Libraries), do you see the Tags displayed there? As I said, if the tags DO NOT show up in Windows Explorer, then the chances are that the ID3v2 part of the file is corrupted, and the only way to fix this is to re-encode the file.
Also, have you tried the taking ownership shortcut?
On other thing I've noticed is that you Music library is pointing directly to your "D:\". Did you re-locate your "My Music" folder there, or did you just add "D:\" to your library and remove "C:\User\USERNAME\My Music"? I moved the "My Music" folder to my K:, as shown here:
Maybe this has something to do with it?
I'm guessing you use WinAmp because you're old-skool and have grown to dislike WMP. This may come as a shock to you, but Windows MEdia Player 12 does a remarkably good job of managing music libraries and locating missing tag information. With the exception of it being a little slow to commit tags to file, it has taken me about a week to locate the missing information for about 400 or so albums in my library. I have also managed to REMOVE about 200 albums from my library after discovering duplicates.
It is unfortunate that many people are missing the advanced features of WMP simply because previous versions of the product sucked big time. In fact, poor performance of WMP in the past is what prompted me to write my own utility ("MP3 Media Properties Explorer") to manage the tags of my music. Now, with WMP12, MP3 Explorer has been relegated to secondary use for those rare cases where WMP i unable to find the album information, and I need to fallback to the FreeDB.org service.
