Artist name like "Surname, Forename"

Hi,
for all artists with a forename and a surname I have tagged and named my music files like this:

Surname, Forename - Title.file

For example "Bush, Kate - Running Up That Hill.mp3"

All Lyrics add-ons I tried do not display any lyrics for files like these.
Of course I could add "Kate Bush" to the Album Artist tag, but that would lead to many duplicate entries.

Is there any workaround for this? I could imagine a kind of a translation table file.

Sorry for my poor English...
