There are many traditional styles in Europe, such as jazz, blues, rock music and so on. These kinds of music have a long history. But China's music has changed little, because our music was developed in the following years ... and the musical instruments are different. Generally speaking, the sounds of European instruments are stronger than those of Chinese instruments.
Now many people like European music, especially pop music. Most people think their music attracts them more. I think the bigger reason is that they have stronger rhyme and can arouse their feelings strongly. On the other hand, most of us don't know the meaning of the song, so we think it is more beautiful.
