Music is easier to be heard and to access. That is why people use music to make their points or trying to make changes in the world. 

There are so many songs that talks about conflicts in the world such as war, poverty, unfairness, inequalities, etc. Music cannot stop these completely, but why people keep on using music as a way of solutions? It is because it is powerful tool that can make these things to be better. We do not realize how negatively those things affect on us. However, by telling us the information and letting us know the problem which may reduce the negative expected results from the conflicts by preventing more problems. Also, the messages of the music are delivered by famous musicians; the effect will be much influential. Such as 21 guns by Green Day has made people know the seriousness of war and try to make a peaceful world. In addition, throughout music, we can help people who are suffering from poverty, or an expected natural disaster. For example, the song “We are the world” was produced to help the poverty in Africa, and it contribute greatly because of the famous musicians had participated in. Yet, the biggest reason is, this music has told, and woken people about people suffering from poverty in Africa. Moreover, a few years ago, there were dreadful earthquakes in Haiti. Again many famous musicians have gathered to help Haiti. They told people in the world about how much Haitians were suffering and how miserably the earthquake ruined their lives throughout their music. It was a great success in helping Haitians. 

Also, music can make people more united. For example, there are national anthems for every single country in the world. Why is that? It is because that the national anthems can encourage the patriotism of the people of the nations. Also, it gives a feeling of similarity with people who sing it together. Additionally, in Korea farmers sing a labor song while they are working, because that makes people feel less tiring and encourage them to work with its hopeful lyrics and dynamical rhythm.
