Add my comment to multiple files

I have taken a large number of mp3's and cleared the tag's so I can re-tag with the file name,
I've done this before.
What I want to know is : Can I add the same comment to all of these mp3's either while tagging them
from the file name or afterwards as a separate option without deleting the tags that are in place eg.
Artist and Song.

Yes, just select all the files and add a comment file, then select SAVE. Can do them all at once and it won't change any other tags (such as artist or title)

Thanks a lot that has saved me so much work. :rolleyes:
