Fly is a song by Canadian singer Avril Lavigne. It was brought out as a charity single (慈善单曲) by the Avril Lavigne Foundation to support the 2015 Special Olympics World Games. The music video for Fly starred Avril Lavigne and Special Olympics athletes from around the world. During a news interview with Good Morning America, Lavigne said that the song has taken on another meaning now following her Lyme disease diagnosis (莱姆病诊断), “(The song is) about inner strength (内在力量) and courage (勇气) ... The message of the song is to show the world that (people) can overcome (克服) ... challenges and that everyone is meant to shine.”
