Music

Music is something that every single person in this world knows (in my opinion).
Music is not just rythm and lyrics, it represents a story or the feelings of the person who wrote it.
There are A LOT of different types of music, some of them related to other, but they all have a purpose and a feeling to share.

The link above will help you see which are ALL the music genres and/or types.

Music is something amazing, it can change your mood or the way you act in a moment. I could not tell what my favourite type of music is, because I like them all. I admire how music makes you feel, is just incredible, how it changes you, how some songs identify to your life. 

Sometimes music can also identify with your life, and that's something I really love about music.
The people who write the music, they are geniuses! They are called Artists. There are a lot of artists nowadays, but there are so much, that there are some that you don't know, but those unknown artists will someday be known worldwide. Music is a way to express feelings, to free ourselves from all the stress and tell other people our problems throughout a song. But music doesn't always talks about problems, it can talk about love, about someone's life, (my favorite is love :3)... Hahahaha thanks for reading this, I really hope you like my opinion ;).
