When korea's two most powerful voices collaborate ... Ahh it's heaven

It would've been cool if ailee sang in English while hyorin sang in korean

Aliee’s voice is like clear ice water. Hyorin’s voice is like soft boiling water. Perfect duet. They are both such wonderful singers. 😍😍😍

Hyorin and Ailee are honestly QUEENS💓

i need ailee and hyorin reunite again..... it's been so long since this and bang bang

I don't understand why this is a competition. They're both technically perfect but sing in different styles. It's all about preference.

They were in sync. not tried to overcome each other. they really are friends.

The two most powerful and wonderful vocalists in the industry come together and create this masterpiece 😭❤️

i dont know why people think hyorin is ugly, i mean look at her she is beautiful .

they look like they're gonna marry each other

완벽한 두 목소리를 한 곡에 담았습니다. 효린이와 에일리가 다시 무대에 섰으면 좋겠습니다. 둘 다 사랑해요.❤❤

에일리 가성 진짜 매력쩐다...

this has the same feeling when mariah carey and whitney houston had a duet... it's too much perfection in one same place

I've waiting years to hear my two favorite Korean singers singing a duet together. So happy :')

October 2019 Who here ? That’s missing unique Queen 👸

The most spectacular singing performance I've ever seen in Kpop! Two of the best singers in Kpop right there. 2:37 Ailee showing that she's one of the very best idol vocalists in kpop. 3:10 Hyorin holding her own on stage with Ailee. 3:34 a flubbed note showing that there was no autotune or post-production audio engineer--they really do sing this well!

This totally should have been korean by hyorin and english by ailee, would have been even more awesome

I'm not lying but this perfect duet gave me goosebumps

미쳤다 진짜... 둘다 완전 실력파야...

Two angels and Queens of Pop. Ailee with clean and powerful voice pairing with Hyorin with sexy and uniqe voice. Just so incredible!

Ailee's voice is loud and clear, while Hyorin's raspy and sexy. Both singers are extremely unique and talented, however, it still depend to the listeners which voice they like more. For instance, I prefer Hyorin's. ;)

for idols who can't sing live, you should be ashamed because of Ailee and Hyorin, this is beautiful, wonderful, amazing

The only collaboration that goes so well only Ailee and Hyolyn 👍👍👍👍

Hyolyn is so pretty!!😊😊 And the way their voices match up... HEAVEN!!

After watching this: Did i just watch this whole song with my mouth opened?

Ailee almost stole all of Hyorin's shine lol it was nice of her to let her hit the long note though lmfao I would love to see these two perform The Boy Is Mine

역시 가수는 노래를 잘해야지ㅠㅠ 본업 잘하는 두 디바의 조합 넘 최고다ㅠㅠ

Hyorin's voice is high and nice, but Ailee's voice is more powerful and that is why I like her

Well, this was flawless. A duet made to be. Now let's do it again but this time in English! :D

I really ship Ailee and Hyorin, Jessica and Taeyeon to sing together. Gosh, Ailee and Hyorin would be the most vocally powerful duet and Taeyeon and Jessica would be the most emotionally powerful duet.

omg hyorin's gonna be a beautiful bride! she looks absolutely gorgeous in that white gown!

Ailee and Hyorin have such beautiful voices, I love listening to them so much ✨🤍

Hyorin outshines Ailee. Her voice suits well to the song. Ailee did also a great job with flawless high notes so as Hyo. Ailee and Hyorin are the same when it comes to belting high notes but their quality differ. Ailee is in strong vocals while Hyorin have a sweet one. Clap, clap for the two. They did an AMAZING job

There's nothing better than *Ailee x Hyorin* :D

what will happen if Ailee, Hyorin, Eunji, and Solar are doing performance at the same stage? i really want to see, hear, and feel it...

와 역시 에일리... 개레전드 보컬

Damn, Ailee's voice has so much body to it! Her vibrato is chilling!

Queen Ailee and Empress HyoRin melting the walls of the ice castle of the northern realm on this Saturday evening ....

March 7th Ailee comeback with her new english digital album... all the support that she deserves from all her fans around the world, let's make something big together 💪💪💪

When you see these two together, get a box of tissue ready bcos it's gonna be beautiful

Oh gosh they completely slayed this song! (I don't like Frozen lol but I love this version) Hyorin's voice is so sweet and strong! Ailee's is amaizngly and epicly powerful! Love it!

that was great. they looked like they were having fun singing with each other, and weren't trying to outdo one another.

i love both their voices so much. ailee's is so strong with great vibrato, and while hyolyn can be kinda breathy, those riffs!!!

Not Ailee and Hyolyn looking like straightly out from heaven. Such a charisma🥺❤️

my two favorite korean female singers together again!!!

I've knew sistar for quite some time and Hyorin is without a doubt a very talented singer. Never heard of Ailee's voice before but it sure is lovely. Both have different type of voice and they compliment each other.

rip to those kpop stans who wasn’t able to see such historical event

ailee and hyroin would make a great duo.

Why bother about who is better when u can just enjoy 2 of the best vocalists in korea performing such a beautiful duet?

Hyorin & Ailee are both talented singers. Their voices blend really well with one another and the harmonies are amazing. Such a beautiful duet among these two

who else is here in 2021 and still hope that ailee and hyorin will reunite

I'm amazed by Hyorin's agility, her riffs are precise and separated very well. 2013-2014 was her prime era ngl. She even had multiple supported notes up there (F5). Ailee? She SANG.

when they put the Golden voice together.. itss BAMMMMMMM.. i hope next will be Taeyeon and Eunji should be together like this

No doubt that Ailee can sing! I've seen her other videos and she always kills it. This time though, I think Hyorin's voice matches the song more. She has that clear and crisp "princessy" voice which matches the song. hahaha but regardless, my two favorite kpop singers ! :)

Ailee KILLED! She has low and high notes!😎

굿걸에서 효린 에일리 다시보고싶다.. 진짜 오지는 조합임데

I read a few comments about Ailee and Hyorin being better than Taeyeon. Seriously?! Why can't everyone just enjoy this marvelous performance and not start a competition about who's better and all. Instead of pointing out each and everyone one of their weaknesses, why not point out their specialties? To start off, Ailee has an AMAZING voice! Her voice gets you hyped up ready to party. Hyorin's voice brings delightfulness and happiness to you. While Taeyeon's voice is very soothing and helps you relax. I don't understand why. People say that Taeyeon's is just average while Ailee and Hyorin are the best. In my opinion, the superior group of beyond perfect voices include Ailee, Hyorin, Taeyeon, Lee Hi, Baek AYeon, and many other artists. I personally prefer Taeyeon's singing, not because I'm a Sone, but because it's to my liking. I also really enjoy Ailee's and Hyorin's singing too depending on my mood. It's based off of everyone's own opinion, so there is no reason to start fan wars and competition just because you are biased. (Sorry for my little rant, I'm not expecting anyone to read this)

First of all, I'm a Blackjack and I passed by this video and watched it since I'm a fan of Frozen. AND THIS PERFORMANCE WAS DOPE! One of the amazing performances of all time. GOT GOOSEBUMPS ALL OVER ME, especially when Hyorin sang that high note in the last part. WOAH! DAEBAK! Hyorin and Ailee really are one of the best singers in Korea. Hands down!

holy crap both of them are AMAZING. NO WORDS.

Ailee is great, even exceptional. I still like Hyorin a bit more in this song, which says a lot as Aylee is great herself. A wonderful video.

I hate this song, but if it's my queen Ailee and my bias Hyorin singing, i won't even think twice about listening to it for 2000000 times

for me, this was the best special stage for today's mucore special!

It's really sound pleasing when ailee control her voice

u can tell from the way they look at each other that theyre friends

im sorry if someone might get offended by this but.. this version is really way more awesome than the original. they made me like the song.. i used to be so annoyed every time i hear this but now it all change thanks to them lol.

hyorin slayed,, i luv dat she can sing so low and sing so high...ailee sounds good in her midrange

Ailee,Hyorin and Taeyeon are the best korean woman vocalists

효린 에일리 듀엣이 진짜 최강조합이었는데.. 또 볼 수 있을까...

Hyorin nailed the low notes! And hyorin voice is so clear..

I know both of these women are amazing singers. But you could really so how much more power Ailee has behind her voice. I really don't think there is anyone who can come close to her ability in Korea. At least in the Idol Community.

THE TWO ICE QUEENS SLAYED TF OUT OF THIS PERFORMANCE. TRULY IMPECCABLE.

Who's still watch in 2019?? 👆👆

This is probably one of the best vocal stages kpop has seen in a while. It was amazing in every sense-- and this is coming from someone who cannot stand this song.

Finally this is the duet that i've been waiting for so long.thankfully it's not like the duet they did before (telephone).yeappp. this one is much much better. in fact this is *PERFECT*. *they're both Beautiful and Awesome in their very own way*. Hyorin melodious voice amazing but i'm totally addicted to Ailee's voice, it's Awesome. She has such a strong beautiful vocal. i love it when Ailee hit those high notes.her voice is so *Powerful* it give me chill every time.

효린은 애절한 느낌 에일리는 환희 마지막화음에 너무좋다

Ailee's voice gave me goosebumps! Her voice has a great energy!!

sick of people calling them the "Beyonce" of Korea. Hells.. these girls don't need to be anyone else but themselves. Holy shiiieeet this was AMAZING. More duets from them please, KPOP CEOs!

I like the way Ailee sings 'Let it go'. there's so much power behind it :')

Hyolyn is my pop queen😍😍^_^ 4me no one can beat her.they are the reason why i love k pop song.

*It's impressive that the two most powerful voices didn't bash each other but made heaven here💓*

Hot Damn SHE IS GORGEOUS. And her voice is so beautiful, Hyorin

LOVE this~ but they both had very different styles of singing it. Hyorin's was sweeter, similar to how she originally sung it for the official Korean Frozen movie. While Ailee's was a bit stronger and fiercer, similar to how the English version was sung. Both different but sounded amazing nonetheless. :)

Ailee would be an incredible Elsa!

omg I'm falling in love with queen hyorin her sweet and powerful voice making me crazy 😍

I was not ready for this at all. Their voices balanced each others out so well, and they both had parts in the song where they shined, and on top of that they both looked flawless! Ailee & Hyorin fighting~

Guys, what do u think if Taeyeon, Ailee, Hyorin are in one mini-group? It will be perfect! 3 best voices in one group! Amazing!

From Dream High 2 to this and now 2019 is almost on its end.

7 years after this song came out and I still can't over it

Ailee is certainly pretty and better at English (she's Korean-American like myself), but it's very obvious that Hyorin is more experienced. Ailee has a nice, cool, deep and high voice but needs to work on control. Hyorin is just beast at singing because its been at least 6 years since she's been debuting. But Ailee does have so much potential, and so I respect them both.

Omg... 3:09 to 3:20 almost made me cry... just a gorgeous high note, you can really feel her emotion, like she MEANS it! Love me some Hyorin

Two most powerful women! Strong, beautiful and their voices are on point!! A fan for life

Best duets in kpop industry. It would be rare to find someone like them these day tho...

Would of preferred they sang in English as it portrays more emotional feeling than Hangul can! Both singers are good in their own right Ailee: deeper, richer and more mature. Hyorin: softer, mellow and pure in tone. Oh and yeah I know music from personal training and I teach children to sing for therapy!!

Hyorin did good job but Ailee killing it ❤️ her voice so unbelievable ❤️

They were SO AMAZING... falling in love with Hyorin, she have unique and powerful voice, meanwhile Ailee So clear and powerfull. Btw Ailee is so beautiful. Oh i cant choose x_x :D... xoxo

Wow Ailee looks like an angel! Love her so much 😍😍😍

*bow down to the qweens* WE ARE NOT WORTHYYY

They sang it together not for us to choose whose better. I know people have freedom to say anything but please respect both of them. They're both great singers😊

노래끝날때까지 스크롤 내렸는데 한국댓글 안보이네...

two angels in one place is really everything! omg
