For those interested in listening to Italian music I’d add Mina to the list, of course, Ornella Vanoni, Mia Martini (whom I’ve discovered only recently, this song where she sings along with Vanoni is pure musical joy:

There was a time (from the ‘60s up to the early ‘90s) when Italian music was ruling over much of Europe (just go to an Adriano Celentano YT video and you can see fan comments written in Russian, German, Spanish etc), it was glorious.
