BARRY Manilow has long been a favourite target of critics for his syrupy songs, but he says he no longer worries about reviews. ''It's so unimportant to me,'' the 47-year-old singer said in Massachusetts. He said that after 20 years, critics were beginning to discover the positive aspects of his works, such as I Am Your Child - the song he sang on the season finale of Murphy Brown. ''My songs have become standards and they will outlive me,'' he said.
