Renaming Deletes MP3 Tag Info - 2nd Request

[Gardner, Joseph A]

Don't know if I missed the answer to this question (I usually read thoroughly, but it's been unusually busy this week ;), so pardon me for asking again:

I'm playing around with the rename files function in an effort to standardize my collection of MP3s. Funny thing is, when I rename an MP3, all the Tag info is deleted. Any idea why this would be so when simply retyping a new name for the file doesn't affect the Tag info? Any advice on renaming MP3s and keeping the Tag info intact? I'm running OS X 10.2 and Rev 2.1.


Thanks!

joe.
