<变脸>.,在一片枪声四起,木屑横飞的枪战中尼古拉斯为那个小孩子戴上了耳机,请问背景音乐是什么?

我特的看了一下，哈哈，

是《Over The Rainbow》
演唱：朱迪.加兰

绿野仙踪(the wizard of oz)插曲,最有名的英文歌曲之一

非常好听

somewhere over the rainbow way up high
there's a land that i heard of once in a lullaby
somewhere over the rainbow skies are blue
and the dreams that you dare to dream really do come true
someday i wish upon a star
and wake up where the clouds are far behind me
where troubles smelled like lemon drops
way above the chimney tops
that's where you'll find me
somewhere over the rainbow blue birds fly
birds fly over the rainbow
why then, oh why can't i?

if happy little blue birds fly beyong the rainbow
why, oh why can't i ?
