Music is the universal language to all human beings, it plays a very important part in our life. It can make us life more colourfully and help us to relax ourselves. Without music, our world would be as a wild desert.
There are different variety of music, such as popular music, classical music, country music, jazz music, rap music, but rock music.
Of all the music, I like popular music better. For the one thing, with beautiful melody, it is pleasant to hear; for another, most popular music deals the topics of love and friendship, which appeals to us young people.
