另外，電影中的配音要角原班人馬全數回歸，更徵召金球獎入圍肯定《西方極樂園》女主角Evan Rachel Wood擔任艾莎、安娜母親的配音工作；除此之外，電影原聲帶更是端出超級豪華陣容：包括葛萊美獎入圍肯定Panic! at the Disco、6座葛萊美鄉村天后Kacey Musgraves，天王級樂團Weezer，以及來自北歐的極光少女AURORA等巨星共同演繹。

　　原聲帶中作為貫穿電影核心的主題曲“Into the Unknown”，是由配音“艾莎”的東尼獎女星Idina Menzel與AURORA共同演唱，另外也邀請曾經與Taylor Swift合唱的Panic! at the Disco詮釋不同版本，堪稱是全新第二代的“Let It Go”神曲；Weezer演出的“Lost in the Woods”具有樂團獨一無二的風格，同時也與電影配樂的形式作出融合，打造令人驚喜萬分的作品。

　　除此之外，“When I Am Older”、“Show Yourself”、“The Next Right Thing”、“All Is Found”都讓人百聽不厭，透過音樂將再次帶領你進入全新冰雪奇緣的魔法世界。
