Δέσποινα Βανδή (Déspina Vandì, Greek singer)

Δέσποινα Βανδή IS Despina Vandi, the reason the name appears in greek is that her international career (of only a few tracks while she has released almost 10 albums in greek) is not enough reason to have her name listed in Musicbrainz in the latin alphabet. For now it is just an alias.

Note also Picard has the option to use the sort name (which is latin) for tagging or file renaming.
