苏珊：这个嘛，也许我会有兴趣的。还有啊，我不知道技术创新的目的是什么，是让我们更快乐还是更烦恼？

Susan: Well, maybe I'm interested in that. By the way, I don't know what is the technology innovation for? To make us happier or unhappier?

有那些谱项链口琴可以吹的？除了苏珊娜生日快乐龙的传人？

Except tunes such as "Susana", "Happy Birthday", are there any more tunes played on necklace harmonicas?
