MP3 tags disappearing?

[hypernova]

After putting some songs on some CDs for my MP3 car stereo, on some of the songs, the tag information keeps disappearing.  Anyone know what the heck is going on?  This hasn't happened before.

they may have bad taggede mp3 files (like they used lowercase instead of uppercase, when they trying to find the tags)?

I have had my tags munched by itunes in the past when a housemate ran it on my shared folder, it was unable to read the tags so just removed them.

Setting his access to the share to read only solved that problem. Perhaps you have a program that cannot deal with the type of tags you have done?

I would suggest using foobar or tag and rename to make sure there is only one set of tags present, and then see how that goes.
