What is the matter with the woman?

A: You look tired today. What is the matter with you?
B: I didn’t sleep well last night.
A: Oh, I am afraid you should try something to relax yourself. How about listening to some music? It works fine for me.
B: I think I can have a try next time. Maybe it will do some help. Do you often listen to the music?
A: Yes, I often listen to the music in my spare life. Music is part of our life.
B: I cannot agree with you more. What kinds of music do you like the most?
A: I like folk music. The tunes are beautiful and the lyrics are introspective. I often listen to folk when I drive. As a matter of fact, I like every kind of music, including classical one, blues, Jazz and so on. I have bought many books about music. There are detained introductions of nearly every kind of music in them. You can find any kind of music in them. I can lend some to you if you like.
B: Fantastic! I think light music is better for me. It is better to be put as background music. It brings me comfort and can make me calm when I am worried.
A: As for light music, I have two tickets of concert tonight. Would you like to go with me?
B: I’d love to. But I haven’t finished my work today.
A: It doesn’t matter. I think I could help you to deal with it.
