France have Edith Piaf, Greece, Maria Callas and Nana Mouskouri; Portugal's Amalia Rodriguez was truly so world class she outclassed the likes of Rod Stewart and Elton John. Britain ? Gracie Fields / Vera Lynn perhaps.
Germany have their immortal Lal Anderson. I forget Russia's national soul of Russian music but she died recently.
We (Spain) recently lost Alicia della Rocha (sadly; but she was a virtuosa pianist. National singers? Who for Spain (female?) I would say male, Julio Iglesias. Any suggestions. Don't tell me that a country like Spain cannot produce a female singer who epitomises the soul of Hispaniola. A Spanish Edith Piaf or Nana Mouskouri.
