Emo is actually a type of music that a lot of teens love. There are some who say that this is somewhat similar to punk music but there are some differences in terms of the lyrics of the songs that are used. There are some who say that emo music is usually more emotional and would usually talk about things that are sad or bad.
Some say that emo people usually do things to harm themselves. They may do it in the form of self-mutilation like cutting himself. There are also some who are overly sensitive and are just angry with the world.
