I'm not into latest italian music that much, but I really enjoy
Elisa.
Elisa
her Wikipedia page
http://en.wikipedia.org/wiki/Elisa_%28singer%29
She sings italian and english both. Her voice is really sweet but powerful at the same time. She sounds pretty different from average italian singer (like Laura Pausini and Eros Ramazzotti our most famous singers in the world) so that's why I like her.
My favourite song from her (and her most famous as well) is
Luce (Light).
Luce won the most famous italian music festival "Festival di Sanremo" back in 2001.

Another song I really love is
Almeno tu nell'Universo (At least you in the Universe).
Actually it's a Mia Martini's cover, but Elisa version is a little bit more sweetier although the original one is amazing as well. One of the best italian love song I've ever heard.
