The importance of being able to express one's self is vital in society to facilitate open communication to and among people. Musicians, as all people, need to be able to communicate openly to other people. In addition, even if nobody wants to listen to what they have to say, the availability of open communication provides a means of self-venting and release of bottled energy.
Not only does music provide communication from the musician, it also helps facilitate communication among those people who may have difficulty expressing themselves altogether. Music can be used as a tool to help foster communication among those who have no voice in society, or those who having difficulty communicating their ideas, concepts, feelings, and emotions to others.
However, sometimes even musicians fail to communicate properly. This category contains song lyrics that may fall short of their intended complimenting or romantic intent. Just think of how many situations in the world could be improved if people could communicate better.
