冰雪女王的主题曲是《Let It Go》。歌词：The snow glows white on the mountain tonightNot a footprint to be seenA kingdom of isolation,and it looks like I'm the QueenThe wind is howling like this swirling storm insideCouldn't keep it in; Heaven knows I've triedDon't let them in, don't let them seeBe the good girl you always have to beConceal, don't feel, don't let them knowWell now they knowLet it go, let it goCan't hold it back anymoreLet it go, let it goTurn away and slam the doorI don't care what they're going to sayLet the storm rage onThe cold never bothered me anywayIt's funny how some distanceMakes everything seem smallAnd the fears that once controlled meCan't get to me at allIt's time to see what I can doTo test the limits and break throughNo right, no wrong, no rules for me,I'm free!Let it go, let it goI am one with the wind and skyLet it go, let it goYou'll never see me cryHere I standAnd here I'll stayLet the storm rage onMy power flurries through the air into the groundMy soul is spiraling in frozen fractals all aroundAnd one thought crystallizes like an icy blastI'm never going back, the past is in the pastLet it go, let it goAnd I'll rise like the break of dawnLet it go, let it goThat perfect girl is goneHere I standIn the light of dayLet the storm rage onThe cold never bothered me anyway!

《Let It Go》是华特迪士尼动画工作室的2013年动画电影《冰雪奇缘》的主题曲，由克里斯汀·安德森-洛佩兹和罗伯特·洛佩兹作曲作词。在电影冰雪奇缘中，伊迪娜·门泽尔为主角艾莎配音并配唱，而收录于《冰雪奇缘》官方音乐带里是迪斯尼歌手黛米·洛瓦托版的《Let It Go》。2014年3月2日晚，《Let It Go》获得第86届奥斯卡最佳原创歌曲奖，伊迪娜·门泽尔在现场演唱了此曲。

随着《冰雪奇缘》一同火起来的这首主题歌《Let It Go》，为这部影片贡献了片中最豪华绚丽的一幕冰上圆舞曲，身负冰封魔咒的女主角——冰雪女王艾莎离开故乡后，试着用自己掌握的魔力在风中载歌载舞，凭空舞出了一座如水晶般耀眼夺目的冰雪城堡，那鲜艳欲滴的色彩，晶莹剔透的质感、辉煌壮观的场景，配上充满情绪张力的居尔特风歌声，看的人心襟荡漾 。《Let It Go》一个流行歌曲，也是一个百老汇歌曲，它是关于一个人心灵上的转变，在电影中还有外形和魔法的转变，所以这首歌是在写一个故事，也是为这种强大精神写的赞美诗。
