If you are talking about ID3 tags, there is software available that will pull the ID3 tag from the filename...

I don't have an IPOD (because I hate Itunes as well) but I have a Creative Labs Zen Micro 8GIG and it reads the mp3 ID3 tags also. I have 40 thousand MP3s on my PC, so you could imagine how difficult this might have been, but I found a program called ID3-TagIT and this helped me rename all my MP3's ID3 tags in one swoop. Now I am good to go!
