听力原文：

MANAGER: Jeff, on your application, you list your current occupation as"musician. "You also say that you're a student Would you mind telling me why you're applying for an office job?
JEFF: Well, as you probably know, it's pretty hard to make a living as a musician. I mean, most musicians work at other jobs during the daytime.

由听力原文可知：

经理：杰夫，在你的申请表上，你把你目前的职业列为“音乐家”。你还说你是一名学生，你能告诉我你为什么要申请办公室工作吗?
杰夫：嗯，你可能知道，当音乐家很难谋生。我的意思是，大多数音乐家白天都在做其他工作。

所以填application：申请表；musician：音乐家。
