I knew someone in a music forum, and she told me that music can be divided into good and bad. I just can't agree with her. She told me that because she is older than me and she listened to a lot of music and she found that some are awesome while some are terrible. I am trying to explain to her than different people listen to and prefer to different musci, but she just cite me a lot. She said this kind of people like this kind of music and that kind of people listen to that kind of music and this kind of people don't listen to that kind of music and so and so on. Finnaly I am speechless. However, I just can't agree with her. So what do you guys think of this? Just give me any ideas that you believe.
