I doubt this would happen to me, but this is good to know. I am anal about my tags and would ensure I would change the files on my computer first, and them re-send them to the MP3 player.
You might consider embedding the artwork into the music files. Less files on the MP3 player that way.
A good (but maybe not "easy") ID3 tagging program is Tag&Rename. It's great for mass tagging and mass renaming files. Plus, there's no music library.
