Check out F(x) - "Red Light"

Nu A-B-O. The ABO stands for the different blood types and the title means new blood. Hope that helps

Fun fact: Luna entered SM as a dancer and she said in the beginning of her training she didn't sing that much. But during training she became the main vocal for f(x)

fun fact other than Victoria they were all only around 15-18 in the MV, Luna was only 17 when she sang this iconic high note 💜

I miss f(x) omg

"Powerful vocals" of course Luna is the best vocalist in sm sadly she's underrated and people didn't recognize her and always feel like she doesn't exist

omg! fx!! 💜 please react fx red light too ^^

2009 is the year of crazy fashion in kpop, almost every group has their distinct fashion that screams so kpop.Not only fashion but every group (2nd gen) has their unique concept and style of songs that people can easily differentiate them, not like this era where there are only 2 types of kpop girl group either you being cute sexy or girl crush.

f(x) is such a great group! They definitely are one of the most experimental girl groups, and have such a unique sound and concept each time. We're really all out there waiting for a comeback 😭 About Amber, she dropped a mixtape earlier in the year so there's plenty to check out!

F(x) is the most unique kpop girlgroup ever : their dance are hard af and their misic are all qualities

I haven’t seen this MV by F(x) in so long and almost forgot how catchy the “na-na-na” was. 😂 Gonna be stuck in my head all day too.

wow i dont know how i feel with f(x) being on throwback thursday like damn i didnt realise so much time had passed😂

This is why i love u, you are the only youtube channel (new ones) who focus on all kpop groups not in few ones.

Oof my childhood 😩

thankyou such react to fx !!! i miss them so much ! more fx please 🙏🙏 and i hope you can react Leo Lyn Blossom Tears next time 🙆

You for absolutely sure should do throw back album reviews!! Bro, the throw backs even on the albums were BOPS. Also, please react to more f(x) soon!

have you seen f(x) red light? or BAP 1004 (angel)? i think you would really like both of those songs!!! love from Houston

OMG YES! Queens f(x) deserve a lot of love and recognition. And boi, Luna is such a powerhouse vocal of SM! If you think she was good back then, now she can burn the entire stage with that voice of hers. I hope you listen to more of them and of Luna's solo work. She's my favorite female singer in SM for sure!

"Electric Shock" "Hot summer" by f(x) ,please watch it thanks for doing a tbt reaction for them i miss them soooo much Krystal is bae

Honestly in f(x) Amber has always been my bias in the group

Love fx-Red light and 4 walls

I wish F(x) would have a come back. I adore Amber, especially.

Oh, also, since you like amber and Luna, check out their song together. It's called Lower

U know that the girl whid yellow stripes in here hair is Krystle she is also an American like Amber

YASSSSSSS PLEASE MORE F(x) THEY DESERVED BETTER. The most unique and talented girl group everrr. And Yes LUNA is one of the most underrrated girl voices in kpop history. Her high notes IS THE HIGH NOTES. Not just random scream. She belts, has vibrato, volume and she catch ya!

React to amber song borders its such a good song, also shake that brass

Yeeeah f(x) i loooove f(x) I love all their songs 😍 Pleaaase do more reaction of them ❤️

React to F(X) - Red light!!!

Boi why you gotta make me stay up late.

React to FX - Electric Shock

F(x) literally has everything talent wise despite just being 5 (and now 4) members. I'm a big SNSD and RV fan but SM really needs to give more attention to f(x). Luna is one of their best female vocalists by far. Amber is their best female rapper. Victoria is among the best dancers. Krystal is just extremely popular and beautiful. They can reach a variety of international fans with their language ability etc etc. They're really amazing and deserve better

Please react to Red Light, Four Walls and Electric Shock I miss F(x) so much SM WHAT ARE YOU DOING? GIVE F(x) A COMEBACK NOW

F(x) has the best b-sides songs. You should listen Beautiful Stranger, Rainbow, Rude Love, Dimond...The whole albums to be honest.

Wow F(x)! I remeber in the past me and my friend tried to cover the dance of Nu Abo for our graduation performance 😭😭 time flies so fast. 💕💙💖

Finally F(x) reaction!!!! Amber is my ult bias

Amber - Borders!!!!!

Tears of joy finally a F(x) view 😭 more F(x) more I say more more more

Pls react to more f(x) their songs are all so good

F(x)’s discography is just simply amazing! If you want to do a throwback album react, I suggest their album Pink Tape! It’s flawless!!

Omg please do a marathon of their title songs. Do La ChaTa, electric shock, (you’ve already seen rum pum pum) red light, and 4 walls at the VERY LEAST cause f(x) is amazing and you can see how they’ve grown through those songs. They’re an amazing group, and SM fucked them over when Sulli left. One of the few girl groups that is extremely versatile and can do just about any genre.

What are your feels about Hot Summer?? MY FAVORITE F(X) VIDEO AND SONG TO REAL!! The outfits are super cute, I love that monochromatic shit.

Omg, thanks! F(x) is unique 😘

Listen to Ambers Mv Borders she wrote and produced it herself

i like your reaction!!❤️ and i miss f(x) so much💔 also check thier songs Red light, Lachata, Chu, Hot summer, Rum pum pum pum, Danger👍🏻

Omg f(x) yes yes !!!! More f(x) plz

YES!! Thank you for reacting to f(x)!!

Oh man I remember when this came out. It felt so fresh and really like something completely new. I loved the promotional pictures for this too, they were so cool.

Please react to their song Chu too and SNSD Genie

YAS THANKS FOR REACTING TO F(X) AS AN MeU IT MEANS SO MUCH TO US 😍❤️ They've been on hiatus for so long and I miss them

If you are impressed by Luna’s voice then you should watch her live performance for “Free Somebody”.

*WHEN I TELL YOU THE 2ND GEN OF KPOP IS THE BEST. THEY ARE THE FREAKING BEST.* Thats the gen i started with im crying i know new gen idols would eventually have their time which is happening now but the 2nd gen will always be the most iconic gen *EVAH* even tho a very few of them are left now in the industry :'))

Now you finally understand why always tell you to check out F(x)💜💜💜💜 .... I wasn’t lying

Yesssss finally you react to F(x) I wait from the beginning you should click Red light and electric shock it's my favorite songs

Can you react to F(x)- Rum pum pum pum

Please do marathon reactions! Like F(x)! Rum Pum Pum, Electric Shock, Red Light, 4 Walls and Luna’s Free Somebody ... you won’t be disappointed!

OMG please react to more f(x)!

F(x) is one of best girls group in K-pop. I hope you check out more.

This makes me miss f(x) more. Hope you'll do f(x) album reviews! 👌

Red light bruh! Redlight! And 4walls!

React to Electric Shock by f(x) please ! It's the best kpop song

The vibe was off the chain

f(x) and SNSD both did a song called "Chocolate Love" as a coordinated promotion - do a two-fer and react to both!

I miss FX so much 💜💜💜 Idc what people say but sulli is my fave

ABOUT DAMN TIME. STAN F(X)

*"Hold on, I like Amber's voice"* , same 💜💜 same 😂

Amber and Luna have two songs together (as a "subunit") called "Wave" and "Lower", plz react, you should love 'em

Crazy fashion that just _should not work_ and yet they make it look _good!_ Thanx for giving the most underappreciated ladies in kpop some love!

F(x) red light please

omg so many memories 😭 good old kpop times

Anyway Dezzy I love your top!!

Seems like you diggin all the old videos. Since you reacted to this video, I recommend you f(x)'s Rum Pum Pum Pum, and Amber's Shake That Brass. It's her song with Tae Yeon SNSD. That's lit too. Anyway, I'm sorry for my bad English :') Thank you, Dez. Much love💜

If you want to get more experience on music, just go w f(x)..!! They never disappoint. Especially their b-side songs, so experimental.

Damn I forgot that Nu ABO was such a bop

Thanks for react to f(x) Please, react more of them, they're a fabolous girl group. I miss my girls so much 😭

Actually 1 member which is Sulli left the group last 2015. It broke my heart since I’m a fan of them ever since their debut and now SM is not giving them any comeback, been waiting for them for a long time already. They are also one of the best girl groups in KPOP. Please react to their song RED LIGHT please! You’ll love that one for sure ❤️

Welcome to the old kpop generation! Not that old but boy, it was such a good time. Unique groups appeared and now they're legend! 😭👍❤️😊

Also the choreography to this song has so much attitude, I love it! Rino Nakasone (the one who made the dance) has been one of the best choreographers in SM history. She's done sooo many dances for f(x), SHINee and Girls' Generation, the most iconic ones in my opinion, like Replay, Lucifer, The Boys and Genie, and more recently she made Bad Boy by Red Velvet and Chain and Boss by NCT. So you can see that her choreographies are very detailed and complex and have a lot of swag! And I'm so happy she still works with SM idols because she's my favorite! This was just a extra fact I thought you might like to know. xD

Yasssss! This is the song that got me into F(x). P.S. I LOVE YOUR THROWBACK THURSDAY REACTIONS

Try rum pum pum pum by fx it is really good

the girl with the dip dye was only 15 in this video, talented at a young age can't relate😅😅😫

You should react to Luna free somebody it’s such a great song

you should watch victoria’s roof on fire mv or dance video! she’s the leader of f(x) and is a chinese member!

Omg finally F(x)!! Always love your reaction More F(x) please!!!

You're a legend! Thanks for giving us two Throwback Thursday videos at once!

Old days ❤️

YAAAASSS F(X)!! They don't get enough love and Amber's solo stuff is fantastic. Check out her song "White Noise" - it makes me feel things.

Bruh your a national treasure for reacting to 2010 K-pop mvs. I wish more reactors were like you.😎👌

Nooo you have to see f(x) 4 walls!!! I’m begging ya!!!! Your life will change !!!

omg thanks for reacting to this vid 😭💓

Electric Shock will probably always be my favorite F(x) title song

Thank you for reacting to these queens. Damn. I miss them so badly. 😭

WOAH did I just see someone reacting to THIS? MY OLD SCHOOL MUSIC!!!! I remember listening to this when I was in 6th grade and now I'm in college it's been a long time!

Thank you for reacting to my girls! I love F(x)!

Ah I wish you reacted to Rum Pum Pum! That song is a musical masterpiece

My god I cried when I see Sulli. Thank you so much man.
