Export music files with original tags


I mainly listen to Japanese songs, so most of the artists’ name is Japanese. However, if some artists are recognised in the database, it will show in English name, it is ok because it also shows the original name. But when I export them into my local drive (for transfering to portable devices) it will export the English name in tag.
I suggest that to give user an option when export to choose whether export the exact file (like copy them) or export files with added(modified) tags.
