i would be very usefull to be able to preview the changes that happen doing the "overwrite genre tag" using last.fm!! (you could review them and change them
)
also i guess that the separator that's being used is the "//" ? i see in mp3tag they show like that and the multiple genres are written each one in its own genre tag...
the option for the tags to be written that way or in the same tag using a separator like ";" could be usefull too! (my most tracks are already tagged like genre; other genre; and i would prefer some consistency!)
also, i guess tha tags are retrieved just by the track tags? an option that you could choose the track tags/artist tags, or combination, which should have more gravity if the first option does not return any results...
(sorry for my bad english
)
