I see a lot of you here are pretty confused. I'll explain it for you, I'm Italian, and a musician after all.
Mi - in Italian it means the note E, but I'm pretty sure what they meant was the word "mio, mia" which is "my"
Amore - is "love"
Cadenza - a "cadence", which is a musical tempo variation or a change in the voice at the end of a sentence, usually in a sweet way.
that doesn't make a lot of sense, but here's the translation an Italian girl can give you!
