I wish this was longer, I would have like to hear that live! it's crazy moving and brought tears to my eyes.

Wow she is the best Female voice in the Music industry no need enhancement no nothing, just she come and sing. Wow this is the real Voice not like the shit we are listening today.

it's so funny when people say she can't sing hahaha she's Idina Menzel for god sakes. I guess people didn't know her before Frozen or something but she is literally a goddess.

Ok for those who post comments like "It doesn't sound like the movie version" "Her voice sounds different from the movie" Ok no, is exactly the same voice. Im quite sure Disney didn't modify Idina's voice, because if you listen carefully, is the same voice from the movie. 
1.- Idina's singing in a private concert, that means the room is not big, let's remember that let it go has some high-pitch notes and are a little bit screamy, so Is not a good idea to sing this song in a small room because it can be annoying to the audience. 
2.- The piano is playing in a different tune, Idina has to sync her voice with the piano. 

Sorry Demi fans, I think she's a good singer but Idina is way better. Im glad because, most of pop singers (girls specially) get their voice modify in their songs, and when they perform at LIVE they sound very different (in a bad way) Idina is not this case, but well.. She's a broadway actress a singer, different shit.

I love Idina! The part where she sings "I don't care what they're going to say" It just has so much feeling in it the way she puts emphasis on certain words... no otherversion beat the english version of this song!! You go Idina!! 

[GumiYummi]

she is flawless i wasnt even sure if i wanted to see frozen until i heard she was elsa.

People seem to be misinformed. They used both Idina and Demi's version for the movie.

Idina's version was, obviously, going to be used during the movie because they're not going to suddenly throw a pop version of the song during the movie. Demi's version was used for the closing credits of the movie. Demi's got more attention because she went to perform it at the Disney Christmas Parade and also got a music video for it.

Elsa's voice really could not have gotten better than this! Perfect actress for the role :)

[AlienCow]

Like her version way more than demi's

[Daniellewhlu]

I like how she adds her own 'style' in when she sings the song

[boop]

Just knowing that Idina is in Glee and she played the best role in Frozen is absolutely awesome ;O

[zoeeeeeeeeeeeeeeeeeeeeeeeeeeee]

I dont care WHAT other people say. You are one amazing singer. GO GIRL!!

[linusekstrom]

First of all: It's a whole other experience hearing a song while watching the live performance to just hearing it. During a this performance you can see her starting of and presumably being a little nervous but as the song moves on to the chorus you can see all nervousity just floating away and being replaced by her passion for this song. It's just amazing.

Second of all: Why the fuck is the video missing a large piece of the song? It's like they just cut the video and jumped straight for the applause.

[firstnamebroflovski]

She just made the movie a million times greater with her spectacular voice ♡ could not have picked a better voice for Elsa.

[MeiButterfly]

Why are you guys comparing Idina with Demi? Idina's trained in Broadway while Demi's trained in Pop.

[TheSingeuse]

Awwwh... That was the very first time we heard that amazing song... :')

[EpicMustache]

I honestly don't understand why people are hating her for this. It sounds the same. :/

[mariebailey]

I am 62 and love this ladies voice. Our Grand daughter plays the Frozen songs dozens of times and I don't get tired of them. Great.

[DigiDestined]

The song is phenomenal in itself.  Demi Lovato does an amazing job with it, but Idina Menzel just takes my breath away.
