I am not from Spain, but I like Mecano; Hijo de la Luna, for example. https://www.youtube.com/watch?v=OwGG5fX7bxY

Not from Italy either, but I have a few albums from Laura Pausini; one of them are cover songs of other famous Italian singers, and one I find fun is Ivano Fossati - La mia banda suona il rock: https://www.youtube.com/watch?v=y9XLiQmFoB0 , also Richard Cocciante - Io Canto https://www.youtube.com/watch?v=dLliBht8KHM Actual Italians may come up with more "modern" suggestions.

But I am Quebecer, and although I could come up with dozens of suggestions, the first one that came to my mind is Luc de la Rochellière - Sauvez mon âme : https://www.youtube.com/watch?v=i4VE10bR_MU
