As David Machin stated in 2010, "lyrics are not just about artists telling stories, but also communicating discourses about their identity." (Machin D, 2010: 78) in fact, the lyrics of a song play an important role in connecting with people and providing people with reflexive identities, when people listen to music, the linguistic meaning offers the audience a better representation of the music and creates a more emotional connection between the singers and the audience. Furthermore, since different music genres have different representational characteristics, the lyrics also differ from each other within the different genres, meanwhile, the composition of the lyrics also changes with the development of the social movement, as Kaufmann discussed, “the industry record company was blamed for causing morally or socially unacceptable behavior, thus placing him in an awkward defensive position.” (Kaufmann, WB, 1986: 225) Thus the regulation of musical lyrics gradually becomes problematic for music creation and the need for music regulation or censorship seems to be increasingly important for the music industry. In fact, the history of music censorship has already emerged in ancient times, and in recent years it has developed from self-regulation to government-regulated regulation. This essay will mainly discuss the historical root of lyric censorship from the early times, explain why censorship is necessary in this industry and finally analyze the problem of censorship in Cee Lo Green's song, Forget You (also known as Fuck You) which is was released in 2010. Musical censorship of lyrics begins at an early age and is usually used to regulate lyrics in rock music due to the furore characteristics of this music genre. So ac... in the center of the paper... the word. In this case, censorship has happened in this song, and by changing the censored word or subtly pointing out the word, the speech in the lyrics can still maintain the original meaning, and in the meantime, the worry of bad influence on children through radio or others types of media have been diminished. To conclude, lyric censorship is a necessary regulation to protect children from being misled, it has been applied to music production and has a strong effect in this sector, however, part of the public and artists still resist this regulation, because it may change the original meaning of the lyrics, and the emotion that the artists wanted to express initially may not be complete in the end. Therefore, it is necessary to apply more intelligence to the creation of texts and make the texts work legally and presentationally at the same time..
