如果有人因为一些小事而做出不相称或不恰当的激烈反应，那么你就可以说“they are making a song and dance about something”；也就是汉语里说的“小题大做”。不过注意这是一个非正式表达。
All right, calm down! You don’t have to make such a song and dance about it. You take the remote control. We can watch what you want to. I really don’t mind.
When I made a tiny comment about his driving he made such a song and dance about it. He was angry for ages.
Don’t make a song and dance about it. You don’t have to have any potatoes if you don’t want.
另一个和 song 歌曲有关的表达是 for a song，意思是非常便宜地。
Quick, if you want a bargain, there’s a sale on at the supermarket. The clothes are going for a song.
In the New Year sales I picked up a new TV for a song. It’s not the latest model but it was a great price.
