Italian pop star Eros Ramazzotti teams up with Puerto Rican pop star Ricky Martin in this duet, “No Estamos Solos” (“We are not alone”—or, “Non Siamo Soli” in its Italian version). Born in Rome, the 44-year-old Ramazzotti is no duet virgin: He’s recorded songs with the late Luciano Pavarotti, Joe Cocker, Tina Turner, Cher and Carlos Santana, to name a few.
