Some think that music has a great impact in society while the others seeing it just as an entertainment, there are no wrong or right in this case because both views are with a reason.
It is true that music is made to entertain people, since the ancient time music have been transforming to any kinds of shape, sound and genre, enduring the flow of time so it can survive in every generation. We cannot deny the fact that we can dance, humming and even sleep just by the sound of some music melody or music percussions, even the sound of rain can be categorized as a music for some people. It is just as simple as that, which is why the music are made for entertainment.
However, our history proves something much bigger about music then just an entertainment. Since the old-time music was used as a media to spread teachings in some religion. For example, most of the religion In Indonesia was spread and taught from music especially Islam religion. I heard that some famous figure that we know today as Wali Songo spread their teachings in the form of music. Another example that music is more than just entertainment, music can be made as the form of protest towards something such as government like what Iwan Fals did. Music can even be a method for students to memorize something from alphabet to chemical compound.
The conclusion is, music are an impactful entertainment, since we can change its shape to anything we want, from something so small to a big role in society.
