Why does WMP 11 (Windows Media Player) not import my songs id3 tag info correctly?

I've used Itunes forever but got a new MP3 player and since Itunes only works with Ipods, I decided to switch to WMP. When WMP searches my computer for music and media, some folders (such as my Gomez music folder) is imported as "unknown artist/genre/album" and the only thing correctly imported is the name of the songs. So when I search WMP for "Gomez" it is no where to be found, but the song is there. If I search for "unknown" I cannot view all the files that were imported that way. If I search for the name of the song, I can view it and play it. Itunes correctly views my Gomez files, but WMP does not. A fix for this? Or is there a hack to use other MP3 players with Itunes?
