Music is of course poetry with a rhythm that can be followed to wit the words of that song. But, Poetry itself is a big way to express you emotions and how you feel when you write it. Music takes it even farther by adding a rhythm that can bring those emotions out even more and give more meaning to your words. For example some songs have no words and is all bass and sound, but still make people feel some way about the song. Like most dubstep does not have words but still makes me feel upbeat or energetic based on the sound and what I hear. So adding words can give a beat a whole different meaning as well. Like when people freestyle rap to a certain beat that has been used by another artist already, Their words give a different meaning to the beat because they are different from the other person’s song.
