...However, this is far too laborious. I would go to that extent if I only had a couple of compilation albums to tag but I have dozens of 'em and doing it that way would take toooooo loooooong.
I am not quite sure that you are familiar with the functions (and actions) of Mp3tag.
Renaming the current folder so that is called like the album field for thousands of files in one go:
1 action of the type format tag-field for the field _directory.
Copying the content of TITLE into ALBUM for thousands of files in one go:
1 action of the type format tag-field for the field ALBUM with the contents %title%
Now comes the laborious part: you have to search for the tag information file by file. But this would also be the case if you had the singles straight away.
Going back to the old ALBUM namefor all the files in one go:
1 run of the converter "Filename-Tag".
If the middle part is too much of an effort - hard luck. But that has nothing to do with the Mp3tag support but your particular likings.
An no, I do not know any WIndows program that might support you. If you installed Linux, you could use puddletag ... (not tested by me but recommended by some in this forum).
