In Mp3tag, try exporting your list with %_path% as the very last column with everything else you want first. As I'm not sure what mess you would get placing it anywhere else and my curiosity isn't getting the better of me at this time of night to find out.
Import this into excel using \ as the delimiter. Hopefully you'll get what I get which is seven columns plus columns starting with your drive letter, then a column for each directory and finely the filename.
You can use %_folderpath% and you will not get the filename in the last column.
In my example you can change all of the \ to what ever like, but you will end up with a few more steps. If using - instead of . You will need to import your file with the delimiter - and then once in excel, highlight the last column which will have the full path and (filename if using), then do a convert text to columns.
Anyway have a play and come back if it all goes tits up for you.
Oh and if I could remember how to get it to output column headings too that would be useful.
