初恋50次里的沙滩男孩演唱的插曲是什么名字？

歌名：岂不更好(Wouldn't It Be Nice)
歌词：Wouldn't it be nice if we were older
如果我们都能更老一些，那该有多好
Then we wouldn't h**e to wait so long
那样我们就不必非要等这么久
And wouldn't it be nice to live together
如果我们能在一起生活，那该有多好
In the kind of world where we belong
在这世界某处只属于我们的地方
You know its gonna make it that much better
你知道那一切都将会更美好
When we can say goodnight and stay together
如果我们能互道晚安并相守在一起
Wouldn't it be nice if we could wake up
如果我们能一起睁开双眼
In the morning when the day is new
在每一个新的早晨，那该有多好
And after h**ing spent the day together
在共度了一整天后
Hold each other close the whole night through
我们仍能一整夜都紧紧拥着彼此
Happy times together we've been spending
如果快乐的时光我们总是一起度过
I wish that every kiss was neverending
如果我们的每一次接吻都永不结束
Wouldn't it be nice
那该有多好
Maybe if we think and wish and hope and pray it might come true
如果我们想的希望的祈祷的这一切都会实现
Baby then there wouldn't be a single thing we couldn't do
那么宝贝，这个世界上就没有了我们不能够办到的事
We could be married
或许我们都已结婚
And then we'd be happy
有着拥有彼此的快乐
Wouldn't it be nice
那该有多好
You know it seems the we talk about it
你知道当我们更多的谈论这些美好的愿望
It only makes it worse to live without it
就会更加难以忍受它还未实现时的生活
But lets talk about it
但是就让我们谈论它吧
Wouldn't it be nice
那该有多好~
