The copyright announcement has angered many veteran musicians. Nguyen Quang Long says the "anthem must belong to the public, and people should be allowed to sing it without worrying about royalties". He adds that Van Cao's name was "honoured in perpetuity as part of the nation's history" when parliament chose it as the North Vietnamese anthem in 1946, and that should be enough. Singer Anh Tuyet, who is best known for her performance of Cao's songs, agrees that the anthem "long ago became a song of the people, so it should be gifted to the people".
