阅读理解。 Music is different from songs. Songs express feelings with lyrics, but music with tones (音调). Unlike songs, music tones in themselves have no specific meanings.   Different people may get different things from the same musical performance. Though some music works are difficult to understand, people need music in their daily life because it brings fun to them.   Different people like different music: some love classical music, and others take pleasure in pop music. Most young people like pop music. Pop music began in the USA and became popular around the world during the 1950s and 60s. The best-known early kind of pop music was 'rock and roll'.   Pop music has taken the place of native music in many  parts of  the world. It has caused the number of people for 'jazz' music to  become much smaller   than in the 1950s and earlier and it has now begun to become the most popular. Much pop music is without artistic value (价值), but the works of some pop singers such as the Beatles, Bob Dylan, the groups like Pink Floyd and Crosby are excellent. And there is still great interest in it today. Pop music concerts and festivals are held all over the world. 1. The biggest difference between music and songs is ______.
