Mass communication genre can be characterized by the use of different kinds of languages. Music, unlike any other communication genre, can help to trace music-language relations in the best possible way. Music is believed to have a bigger power over the human emotions than the language, though when it comes to the language of the songs, music and language change their roles. People tend to listen to both the lyrics and the music of the song, and one cannot deny that that if any of these constituents lacks the power to impress the listener, the song will never be considered a success. Lyrics of a song lets the audience perceive the idea of the song and the emotional load it is supposed to carry, whereas the music helps to convey the emotions and inner character of the singer. The songs of different genres are written in different languages, which has certain impact on the audience of a singer and the effect the song produces on it.
