Music have influence on how people look and behave. I agree with this opinion but not completely. Music is an element of culture with which people are identifying. They often take inspiration of clothes from their favourite artist. For example people who listening to rap usually are wearing tracksuits. Music has influence on people also because it has areola around oneself. Majority of subcultures has favourite type of music. Through fascination they can fit their clothes to type of music. For example people listening to metal are Goths and they're wearing black Doctor Marten boots, long black coats and black t-shirts with the names of their favourite bands on them. However we shouldn't evaluate people by clothes because not each identifies with the type of music. If we see a person who is wearing a tracksuit this person don't have to listening to rap and be bad. Not each who listening to reggae is a rasta and has dreadlocks. Some people wear the comfortable clothes and the don't pay attention to music.
So the music dosen't always has influence on how people look and behave.
