III. Listen, complete and retell. 

There are some differences between rock and pop music. Most pop singers use the music to make money and become rich and famous. Rock singers, on the other hand, make music their life. They play music to make themselves feel better and happier. 

Pop songs and rock songs are written in different ways. Pop songs are usually written by other musicians. The singer often knows little about the ideas or feelings behind the song. As for rock music, however, the singers and musicians are all able to write music and work together in a band. When one of them has a strong feeling, he or she expresses it with music and the others help build the song.

Rock and pop songs tell different stories. Most pop songs tell simple stories to make people happy. Rock music, on the other hand, expresses true feelings. Pop music makes people feel easy and forget about the real world; rock music makes people think about the world and how to make their life better.
