First of all, MP 3 tag is the best. Now that we got this out of the way, here's a tech question.
I want to assign the value from the "artist" field into the value of the "album artist" field for about 400 different files. The do not have the same values for "artist" so it needs to be a variable function that will simply transpose the correct value for each file tag. Is this possible??
thanks!

Thanks!
Is there a published list of attribute field variables, such as %artist%?
