Singer-songwriter Sinead O’Connor has died at 56. The Met Police said O’Connor was found unresponsive in a home in southeast London. They did not say how she died but said her death was not considered suspicious. The gifted and troubled Irish performer was known for her shaved head and fierce and expressive voice. O’Connor, who began her musical career singing on the streets of Dublin, was a star from her 1987 debut album “The Lion and the Cobra.” She became an international sensation in 1990 with her cover of Prince’s ballad “Nothing Compares 2 U.” In 1991, O’Connor was named Artist of the Year by Rolling Stone.
