Hi I am italian, I would an opinion about these songs?

These are italian songs, I think these songs are very beautiful, but
they are only in Italy, can you give me a opinion? Only for curiosity.
The songs are (I write "name band or artist - title song):
1) Negramaro - Singhiozzo (mean "sob")
2) Emma Marrone - Io son per te l'amore (mean "I'm for you the love")
3) Finley - Il mondo che non c'è (mean "The world that there's not")
What is the best? and the others songs? Thank you.
I think you can listen on Youtube, or iTunes, on web there are many
programma of music.
PS: Is "I would an opinion" or "I wanna an opinion" or other?
