Can you recommend me some good songs in Italian!?

Yes, of course! I believe we have very fine singers and musicians, here in Italy.
I will add to my answer during the week, as right now I don;t have much time.
Let me start with Lucio Dalla, that sadly died just recently.
-- Nuvolari ;
-- Itaca ; -- Ulisse Coperto Di Sale ;
-- Anna e Marco ;

-- Caruso (1985) (many people think this is one of the best Italian songs ever;
lyrics and English translation are here:
url: en.wikipedia.org/wiki/Caruso_(song)

-- Futura
-- Cosa sara` ?

-- Mela da scarto (1975) Quite a peculiar song, I just love it! It has
a moving 'fisarmonica' sound in it; it is a simple and nice tale about how
life could go turn in the wrong way.
(some sentences need an explanation, but they are beautifully constructed; note: Ferrante Aporti is the name of a juvenile detention-educational centre near Turin - Torino)
-- Amore disperato (he used to sing this song with the great female singer Mina)
Italian lyrics may be easily found, for instance here:

--- Caterina Caselli: Nessuno mi puo` giudicare (1967, yes before the moon 'landing' ! in 1969)

-- Tiziano Ferro (metallaro?) : Ed ero contentissimo (2006?)

-- Ivano Fossati : La Volpe (a beautiful and short love song; quite easy to understand the words, I think)

-- Ivano Fossati: Il canto dei mestieri
-- Ivano Fossati: La Costruzione di Un Amore
-- Ivano Fossati: Notturno delle tre
-- Ivano Fossati: L'orologio americano

-- Enrico Ruggeri: Primavera a Sarjevo
-- Enrico Ruggeri: Contessa

-- Franco Battiato: Perduto amore
-- Franco Battiato: Cuccurucucu
-- Franco Battiato: Atlantide

-- Donatella Rettore: Donatella
-- Little Tony: Cuore Matto (1967)

-- I Nomadi: Dio e` morto (writer: Francesco Guccini); don't fear, resurrection is also cited in the song.

Beautiful songs also from Lucio Battisti, Fabrizio de Andre' (more to say later)
