《何以笙簫默》裡面有兩首英文歌，分別是電視劇版的插曲《The Road Not Taken》和電影版英文主題曲《You Are My Sunshine》。

1、電視劇版插曲《The Road Not Taken》

由新晉唱作女歌手高姍創作並演唱的歌曲。首次出現在電視劇《何以笙簫默》第十三集結尾女主角在男主角家門口等男主角的時候。原文為美國詩人羅伯特·弗羅斯特的短詩。

歌名：The Road Not Taken（未選擇的路）

演唱：高姍

歌詞：

Two roads diverged in a yellow wood

I"d go back and rechoose if I could

But here I lay now, sick and so confused

Was it a lie or was it all true

Sleep now gently my darling love,

Don"t let my worries trouble you

People try hard to forget

But memories always stay

Nightmares and dreams of long passed things

Try and chase me away from sleep

All that time I spent in the dark

Just like that; I"m in the light;

Everything will be fine

Notice all the similarities

We go together like the birds and bees

Just imagine what all could have happened

Every one I knew would long be dead

What really goes on behind closed doors

Makes me secretly cry out loud

Within all these horror stories

Lay many times of regret

Always in such a frightened state

Trapped in an imaginary cage

Living life day by day

And soon enough; some day;

I"ll come out and play

In a world where everything is upside down

I try hard not to lose my mind

Things keep getting worse so

I tell myself everything will be fine

I want to grow up and be a real Rebecca

In the end, it"ll work

2、電影英文主題曲《You Are My

這是中國歌手張靚穎演唱的歌曲，由Jimmie Davis作詞作曲，張靚穎擔任歌曲製作人。

歌詞：

You are my sunshine

my only sunshine

You make me happy

when skies are gray

You"ll never know dear

how much I love you

Please don"t take

my sunshine away

The other night dear

as I lay sleeping

I dreamed I held you

in my arm

When I awoke dear

I was mistaken

So I hung my head and cried

You are my sunshine

my only sunshine

You make me happy

when skies are gray

You"ll never know dear

how much I love you

Please don"t take

my sunshine away

So Please don"t take

my sunshine away

You are my sunshine
