Hobby is one of the most important things we should have in our lives. It is something that brings relief of the daily grind and allowsyou to relax. Of all hobbies in the world, I like music the most. For me, music is the best hobby ever. You should look around and you can see that music everywhere. I enjoy music and I listen it very single day. There are a lot of different styles of music for you to choose and enjoy. If I amin good mood, I prefer to listen some energy rock music that keef me happy and full of power. If I am tired I choose some calm, relaxing songs. Music can speak though music people can express feelings and emotions. When you hear something that looks like you, that you understand it easily, you start to love it. There are several different ways to enjoy music as you hobby. When you discover an artist or musician that you satisfies, it's clear that you want to collect all of their works. Not only listen to music, a music collection is a great hobby to have, too. Music is a hobby that has no boundaries. It makes the worlds small. Without music, life would be a mistake.
