Who couldn't fall in love with that girl. With that personality and vocal talent she will conquer the world.

4:41 I felt her anguish, sorrow, despair and sadness with this moving rendition of "Tomorrow".Hands down this is the best version I've ever heard in my life.

THE BEST version I’ve heard in my life. Beautiful. Love her charisma, attitude, and quirkiness 😂

Probably one of, if not , the best first auditions i've ever seen.

As Simon said, her control was unbelievable.

SHE DESERVES THE GOLDEN BUZZER!

I’ve never heard this song sung with such passion ,outstanding!! ♥️♥️♥️she deserves the golden buzzer and then some .

I've watched this 4 times, and I cried every time. The last time I shared it with my daughter, and she started crying, too. There is something very magical about this performance.

I love her!! Not only an incredible voice, but an even better personality... She is just delightful! She definitely deserved that golden buzzer.

What a stunning audition. Her rendition was soft, powerful, full of emotion, bold; I could go on and on. I think for the first time ever I felt connected to every line she sang. She told a story and gave this song the depth and meaning it was always meant to evoke.

I've heard this song a million times. But this rendition made me cry. Looks like tomorrow is all grown up.

I love her supportive Grandmas so much ❤❤❤

Can we talk about the video editing for a second: Thumbs up to the incredible video and music editing which made the entire Golden Buzzer moment spectacular all through the end when Sydnie hugged her family. WELL DONE EDITORS!

She’s going to be a star . Utterly incredible ⭐️⭐️

What a vivacious positive personality! Her version of Tomorrow is the best I’ve heard. ❤

Beautiful in her own unique way of singing this song. Talented yes yes yes!!!!!

I know why Simon hated that song... he never believed the lyric. Now he does... so do I. Thank you young gym lady.

She's the "whole package." Can't wait to hear her sing again ❤

My God..!! That was absolutely breath taking..! I think I've fallen in Love...!!

Best version I've heard so far. Now that's the record to break

What a talent. Pure tallent. Nothing beats it

Her control her persona her big smile ....man this is stupendously fantabulous

My God, this was outstanding. She told us a story. She's a storyteller, a beautiful and outstanding performer. May God Bless Her.

Great voice,, face of an angel and humor to boot. You got it going on girl.👍

There are no words to describe this girl, an outstanding singer, incredible persona just an amazing attitude.. All the way around she seems to be a beautiful person with huge talent skills 🎉🎉.

What a lovely person. She deserved that applause.

Never knew Tomorrow could be sung with such jazz and soul😊❤

That was one of the most beautiful songs I have ever heard! It was like a brand new song even though it has been around for centuries! Breathtaking --truly!

First of all she was really naturally funny but when she started singing that song it was really so good.She sang that song with so much old time soul and made it her own...Goodluck Christmas!

My goodness! She has a beautiful distinc voice. Wow! She is definitely going to be remembered.

I’ve never ever heard this song sung so deeply felt in my heart. 💜 thank you.

She needs to become a STAR..she is beautiful, very funny and THAT VOICE..come on Simon..

I watch this several times. I cry each time. I want a recording on Apple so I can add it to my collection!

Someone needs to build a comedy, singing sitcom around her. Uk has so many good comedian writers, that i can see her in television and in theater. I wish her the best future ever. She makes people laugh and smile. What a gift. 😊

Wow! What's not to love? Sydnie, You're quite simply, everything this world needs! You're Personality, looks and that amazing voice! The West End should be praying for the time you step on stage! 💞

She was incredible in every way and could lead any musical show on any world stage or movie!

That was in a league of it's own! Amazing!

Old soul singer. Amazing. She reminds me of Jane Seymour.

I can't stop listening to this. Absolute perfection. She's already a star ⭐⭐⭐

She is so lovable, talented, and her personality is infectious! She sang just beautifully! I was captured for sure!

Full on talent. Bigger on Personality. Perfect.

That was The BEST RENDITION I EVER HEARD OF THAT SONG..😁👏👏👏

The BEST version I've heard in my life.🥰

This is the 2nd video I have watched of this performance and it is just too powerful and pertinent to today's Humanity struggles. I cry everytime.

She's funny, she's lovely, and she sang that song beautifully!

That’s the best singing audition that I have ever seen on this show! Wow! 😮❤❤❤❤❤❤❤❤❤❤❤❤❤

Hard work and perseverance gets you to the top. Well done young lady, awesome. Well done

She sounds so much like Barbara Streisand! Thank God! So glad she got the golden buzzer and cant wait to hear her future! ❤

A grown up version😊Absolutely beautiful....

Such a beautiful soul that girl has. I've never seen someone who could light up room like little miss Sidney can. She has the world in front of her. God Bless You beautiful.

Beautiful, absolutely deserved the golden buzzer.

Beautiful.... Both her voice and her look

Absolutely phenomenal performance. She deserved that buzzer moment. I would actually like to hear her sing this song playing Over The Rainbow.

This was a Tony Award winning performance of this song. Vocal control like no other. To have so much vocal strength and that soft lilt to her voice. Impressive!!!!!!

Simon said it well: “I used to hate that song and now I absolutely love it!” Best version I’ve ever heard!

She's cute, funny, fun, personable, everything about her made me fall in love with her instantly. As she sang I couldn't help but notice the physical aspects of her performance. She kept her eyes up, looked at her entire audience by changing where she looked a she went along, changed her stance and how she held the microphone and its stand. She changed how she held her arms in ways that actually accentuated what was happening in the song as it went along. She looked like a long time, highly experienced stage performer. Then of course there's her singing itself. Exquisitely controlled dynamics, flawless phrasing, perfect voice control every step of the way. And that finish! Oh.. my.. god. Going from those huge powerful notes to a softer voice and volume in one note. That simply took everyone's emotions right back into her hands and set us all forward to hear what was coming. And then her face, her eyes, her body became subdued and we saw a touch of moisture in her eyes. Finally her voice diminished and fell off, still with faultless control, and left for a moment almost falling forward. That was the moment tears came to our eyes, and a void stood for only a moment before we poured our applause into it. Sydney showed herself to be one of the best singers and stage artists I have ever, ever seen. On a scale of grade school to grad school, Sydney would be a senior professor, college dean, nationally sought after expert, and superstar. Hooolyyy cats! I love her. I'm a total fanboy. I would fly to the UK just to see her perform in the West End. ❤❤❤❤❤❤🤩🤩😍😍😍💖💖💖

Stunning Arrangement! Love..Love her Incredible Voice!! God Given Talent! Beautiful ❤🎉👏 Omgee's!! A Star 🌟 is Born!!

Never heard a rendition like that. Beautifully nuanced.🎉🎉🎉

The way she said "I love you" towards the end of the song along with her facial expression! Wow!!!

TOP talent in all the years I have watched!!!!!

Simply the best. Every single note is already a melody to consider and she put them all together to form an ensemble of the best sound it can produce. Music sang at its best. And it looks like the singer is the one directing the accompaniment playing in the background. 🙌🙌🙌

Full body chills and goosebumps

I cried.. I've always loved this song since the first time I heard it.. Thanks so much, Syd.. You did it justice. Beautiful.

Brilliant touching A star is born

When she's singing, it's like she's a different person. She just beamed with light. Amazing.

Feels like I’ve just witnessed the whole and every scene of a some tremendously gorgeous movie. This is way more than a 4 mins of singing, it is conceivably the most powerful and heartfelt storytelling in terms of how beautiful and hopeful our tomorrows are. What a powerhouse performance. Still can’t find the best word to describe this.
