听力原文：W: I saw a really interesting program on TV last night. It talked about the type of things that record companies have to be careful with when they come out with new CDs.
M: What do you mean？
W: Well, they have to be very careful not to offend people -- especially parents with young kids who might buy a CD that contained violent content or used strong language.
M: How can that be avoided？
W: Well, don't you remember when that woman -- some senator's wife, I think, made a fuss over this issue？ It's not really a law, but music companies are now encouraged to put a warning label on albums that describe violence or use strong language.
M: I don't understand. Doesn't that reduce the musician's freedom of speech？
W: Not really. Musicians still have a right to free speech, but the message on the label says, "Buyer, be careful: if you get upset by violence and ugly language, don't buy this album." You agree with that, don't you？
M: I don't know. I still think the whole thing is funny and unreasonable. Musicians should have the right to say what they want to say without having to have a warning label put on their music, I mean, who gets to decide what is considered offensive and what isn't, we don't need a sticker to tell us what to do!
