在《歌喉讚2》中由安娜坎卓克Theresa Anna Kendrick飾演的女主角貝卡在唱片公司中為了向製作聖誕專輯的老闆毛遂自薦，表演了一段巧妙的歌曲重唱，讓唱片公司老闆耳目一新。片中這個公司是請來Snoopy Dogg 以嘻哈風演唱了傳統聖誕歌曲〈Winter Wonderland〉，貝卡則搭配了〈Here comes Santa Claus〉。
以下是電影片段~
是不是很特別呢？
其實學過音樂的都知道，這只不是一種很簡單的音樂手法，譬如只要節拍符合，調性符合，旋律是以CGAEF (此處為舉例) 進行，則任何符合以上原則的歌曲都可以輕易融合在一起，不會有違和感，這也是阿卡貝拉的元素之一。難怪片中的製作人老闆對此稱讚貝卡時，貝卡說：「這沒什麼，因為我是唱阿卡貝拉的。」由Snoopy Dogg所唱的是傳統歌曲〈Winter Wonderland〉，原來並不是針對聖誕節而作，但流傳久遠後，它就變成聖誕傳統歌曲排行的固定嘉賓了。以下是一個傳統版本，就是在聖誕節前各賣場都會播放的歌曲~
原詞如下：
Sleigh bells ring
are you listening
in the lane
snow is glistening
A beautiful sight
we're happy tonight
walking in a winter wonderlandGone away is the bluebird
here to stay is a new bird
He sings a love song
as we go along
walking in a winter wonderlandIn the meadow we can build a snowman
Then pretend that he is Parson Brown
He'll say: Are you marriedwe'll say: No man
But you can do the job
when you're in townLater on
we'll conspire
as we dream by the fire
To face unafraid
the plans that we've made
walking in a winter wonderlandIn the meadow we can build a snowman
and pretend that he's a circus clown
We'll have lots of fun with mister snowman
until the the other kids knock him downWhen it snows
ain't it thrilling
Though your nose gets a chilling
We'll frolic and play
the Eskimo way
walking in a winter wonderlandwalking in a winter wonderland
walking in a winter wonderland而由貝卡所唱的〈Here comes Santa Claus〉，是由貓王Elvis所原唱呢！
原詞如下：
Here comes Santa Claus, here comes Santa Claus
Right down Santa Claus LaneVixen, Blitzen, all his reindeer
Pulling on the reins
Bells are ringing, children singing
All is merry and bright
Hang your stockings and say a prayer
'Cause Santa Claus comes tonightHere comes Santa Claus, here comes Santa Claus
Riding down Santa Claus LaneHe's got a bag that's filled with toys
For boys and girls again
Hear those sleigh bells jingle jangle
What a beautiful sight
Jump in bed and cover up your head
Because Santa Claus comes tonightHere comes Santa Claus, here comes Santa Claus
Riding down Santa Claus LaneHe doesn't care if you're a rich or poor boy
He loves you just the same
Santa knows that we're God's children
That makes everything right
Fill your hears with Christmas cheer
'Cause Santa Claus comes tonightWell, here comes Santa Claus, here comes Santa Claus
Riding down Santa Claus LaneHe'll come around when the chimes ring out
It's Christmas morn again
Peace on Earth will come to all
If we just follow the light
Let's give thanks to the Lord above
'Cause Santa Claus comes tonight
'Cause Santa Claus comes tonight以上兩首如此應景的歌曲是不是很有氣氛呢？〈Winter wonderland〉是溫厚傳統的聖誕歌曲，創作於1934年，由作曲家Felix Bernard及作詞家Richard B. Smith所作，中文名稱亦稱〈冬日仙境〉；而貓王Elvis的〈Here comes Santa Claus〉，則帶有歡欣的搖滾味道。喜歡阿卡貝拉的朋友不妨利用假期，將妳所喜歡的聖誕歌曲或合併或和音，加入beat-box，創造屬於你自己的Pitch Perfect！《歌喉讚2》原聲帶中獻聲演唱〈Any way you want it〉的阿卡貝拉團體『五聲音階Pentatonix』曾經出過一張聖誕專輯，文末便用他們的〈Little Drummer Boy〉祝福大家冬日愉快！
