听力原文：W: You went to the Grand Concert Hall yesterday? M: Yes. It was really fantastic. W: You are crazy about music, aren't you? M: Yes, I am. It is always my favorite. W: What type of music do you like most? M: I enjoy listening to all kinds of music—classical, jazz, rock and roll...but my favorite is pop music. W: I like pop music, too. But my favorite is still country music. M: Country music? Then you must know John Denver and his songs. W: That's right. I'm familiar with all his songs. I like 'Country road takes me home' most. Unfortunately, my cassette-tape recorder broke down the other day. M: Oh, have you thought of buying a new one? Or buying a CD player instead? W: I've no idea. I don't know which I should choose. M: A Walkman is easier to carry, but the quality of the sound is not as good as that of a CD player. A cassette often produces annoying 'hiss' sounds while playing. This is the reason why I myself chose a CD. W: I have a question. Nowadays, many digital products like MP3 and MP4 have appeared on the market. Will they replace CDs completely and make them outdated? M: It is hard to say. You'd better find more information about all these products before making a final decision. (20)
