"Mi Mancherai" is actually an Italian song by composer and musician Umberto Tozzi, which Josh Groban covered for his album "Closer." The song is a deeply emotional ballad about the pain of lost love and the struggle to move on and find closure. In the lyrics, the speaker is grappling with the end of a relationship that they had hoped would last forever. They reflect on the passionate moments they shared and the promises they made to each other, but now it all feels like it was just an illusion. They can't believe that love could ever be so fragile and fleeting, and they feel betrayed by the person who was supposed to love them. As the song progresses, the speaker begins to find some small comfort in the idea that they will never fall for the same lies and false emotions again. They vow to never again be vulnerable to the pain of lost love, but at the same time, they recognize that the dream of love will always be a part of them. Overall, "Mi Mancherai" is a powerful and poignant exploration of the complexities of love and heartbreak. Josh Groban's haunting and emotive performance captures the raw pain and longing at the heart of the song, making it a moving tribute to the power of love and the human spirit.
