Larry - a quick solution for yours seeing as its just something you want to do as a one off:
Create a new temporary field that is NOT stored to the file, copy all your album names to that field, update from tags then copy back from that field to the album field.
That should do it for you.
And Matt - MC is a great general tagger but it's not nerdy enough so to speak.
I have a Cowon D2 which is very anal about tags - if they're at all off then the library in the D2 goes totally wonky so I have to make sure all my tags are spot on.
I need all my mp3's to be id3 v2.3 and also need to make sure all cover art is embedded into the songs.
AFAIK there is no way to see the id3 version number of tracks in MC whereas with mp3tag this is just one of the columns so after I let it scan all my files, I click this column header and can instantly see which tags I need to re-write.
I also do the cover art at the same time just for simplicity as I can instantly embed it while re-writing all the tags.
Just as an additional idea that I had while tagging my files yesterday, I want a large quality image for my music obviously but storing a 500kb image file in all my images resulted in a 5Mb increase in the album size. Doesn't sound like much but when you times this but 100 albums I have suddenly lost 500Mb of space on my mp3 player.
A VERY cool feature for MC would be if it's album art feature could be 'smart'.
Currently it offers to save a copy of the image into the files as well as into the folder/specific folder/etc.
It'd be GREAT if we could tell it to save a smaller sized copy into the files and a larger quality copy into the folder.
Then I could have a single 500Kb file saved with the album and then have each track just embedded with a 30kb smaller file (all thats needed for my mp3 player).
Just an idea and one thats probably way too much for alot of users but just thought I'd throw it out there
