Avril Lavigne, 33, has finally released some new music after three years. Head Above Water, the lead single (主打歌) from her new album, came out on Sept 19. But you can’t blame (责怪) the talented Canadian singer for making her fans wait for so long. She has suffered from a serious disease since 2015. The singer said that writing songs for her new album helped her stay positive. She wrote Head Above Water from her hospital bed. “Those were the worst years of my life… my music helped to heal (治愈) me and keep me alive,” she wrote on her website. She said she hopes her music can bring others strength.
