We really need a way to distinguish artists that share the same name.
I thought about adding a new column in tblartists: UniqueArtistName.
This field could be used similar to discogs names with a unique number in brackets after the artist's name.
Another way would be to use ArtistName similar as discogs names, and then leave out the brackets-part in views and when sending information to last.fm.
A workaround is to use Discogs style, Artist (1), Artist (2) etc. Artist (Country) can of course also be used, it's up to the end-user I think
