Krystal: Aye Ay Ay Ay Ayeee wait a minute Me: Iconic. Legendary. Amazing. Spectacular. Beautiful. Perfection. Gorgeous. Extraordinary. Remarkable. Fantastic. Exquisite. Stunning. Wonderful. Ground-breaking.

*f(x)'s Red Light will always be one of Kpop's best comebacks of all time.*

I don't think any other girl groups would ever do this half-half makeup. F(x)'s concepts and songs were always so unique. Hopefully they have a comeback soon.

에프엑스 컨셉 중에 단연 1등이라 생각하는 곡. 9년이 지난 지금 봐도 이렇게 세련될 수가...이 컨셉 그대로 뮤비도 다시 찍을 필요없이 지금 다시 활동해도 하나도 이상할게 없는 세련된 컨셉과 영상. 1:07 설리 웃참 실패 ㅋㅋㅋㅋㅋㅋㅋㅋ깨알같은 귀여움 3:11 갑자기 슈퍼파월깨발랄한 빅토리앜ㅋㅋㅋㅋㅋㅋㅋㅋㅋ이건 웃참도 아니얔ㅋㅋㅋㅋㅋㅋㅋ 멤버 한명한명 다 컨셉을 100퍼센트 소화하고 너무 멋지다ㅠㅠ 그야말로 마스터피스!

That beat in the chorus is so frickin' original and DAMN that girl has a voice for rap. Woah.

The concept is such a masterpiece

Stop using Sulli's name to gain likes already. Everyone coming here for a reason so don't bother asking who's here after someone's lost. It's heartbreaking, I think it's time to pay love and respect, not time to looking for likes.

To this day, F(X) will have a special place in my heart. They were Shinee's sisters for a reason and i'll always be mad at SM for forgetting about this group

not many people realise how great of a song this is... cries

If this was released around 2019-2020 everybody will be freaking out. f(x) is just ahead of their time.

Fact: It was said that Sulli wanted to leave even before Red Light. The hate towards our Giant Baby Jinri started in Rum Pum Pum Pum era. An audience told Sulli that she should lose weight. The hate was too much that it convinced Sulli to leave. The members convinced her to stay, so she did. That. That is a strong woman. She wanted to leave because the hate was affecting her group, but she stayed because of her members. That's what you call, bravery. Sulli was a warrior, and still is. f(5) will always be my first group.

for new fans. 0:36 Luna: Main Vocalist, Lead Dancer. 1:53 Victoria: Leader, Main Dancer, Vocalist, Rapper. 2:52 Amber: Main Rapper, Vocalist. 3:08 Sulli: Visual, Vocalist, Rapper. 3:20 Krystal: Maknae, Lead Vocalist, Visual, Face, Center.

This hits different when you haven't listened to it for years

lets admit if this was released now everyone would go crazy

No groups will ever be as aesthetics as f(x)

거의 10년 전 노래지만 여전히 세련됨... 뮤비도 그렇고 헤메코도 그렇고 어떻게 이렇게 잘 뽑았지

Miss their unique sound and style. SM, please give us a comeback. :(

f(x) were truly ahead of their time. Their discography is one of the best in k-pop and I'm not even over exaggerating. Nobody, has ever touched their level. SM tries to outdo f(x)'s discography, but never can. Their uniqueness is something which cannot be matched by any other group.

Nobody was ready for f(x) at that time. They and their concept was for years ahead.

f(xx) will always be that girl I will never forgive SM for forgetting about this group

After all these years this song still unique !

첫사랑니랑 이노래가 요즘노래보다 훨씬트렌디한듯; 너무아깝다진짜

지금 나와도 너무 세련된 곡 내 기준 에프엑스 노래중에 제일 좋음

0:33 SULLI LOOKS INSANELY COOL I CANTTTT

f(x) should’ve debuted later. like years later. if this music video came out 2017 or later they would be THE group now.

SM definitely just simply forgot that f(x) is their child

Red Light was one of the greatest concepts SM ever did.

이 컨셉이랑 앨범이 진짜 좋았음. 이 곡이 훨씬 더 흥했어야 되는데.

Red Light was definitely ahead of its time. I wish SM hadn't mismanaged f(x).

Nobody can do the experimental music the way SM does. And nobody perfects & owns the genre like SHINee and f(x) did. This is way ahead of its time. But I'm so glad I got to enjoy this when it dropped. Miss my girls

That harmony between Amber and Luna at 1:33 is legendary

happy 10th anniversary to one of the best kpop releases of all time

4 years later and this is still one of the most amazing songs to ever come out of the entire kpop industry

Stop remembering Sulli as "the famous idol who killed yourself" remember her as a strong, warrior woman. Because, it wasn't her who killed herself, people killed her

i can't believe f(x) invented the dark concept and the red color of light

진짜 신기하다.. 8년 전인데 어떻게 곡 분위기나 스타일링이나 하나도 안 촌스럽지? 지금 나왔다 해도 믿겠음.. 핑테부터 해서 참.. 시대를 앞서갔네 민희진도 스엠도 약간 무서울지경임

Today marks six years since the sewol ferry tragedy. Rest In Peace to all the people who were on board.... it breaks me how the students would’ve been adults by now. Thank you f(x) for making this song as a tribute to the victims

SM,we need something like this in 2019,it's their anniversary ffs

SM, PLEASE MAKE THEIR COMEBACK. NEXT YEAR IS THEIR 10TH YEARS ANNIVERSARY OMFG. LET THE NEW GENERATION OF K-POPERS KNOW WHO THEY ARE🙇

They really released this when every other girl groups were going "whoo!! It's the summer! Beach balls and water everywhere!" f(x) was like "nope, eat my ammo!"

All of them could literally be visuals. Krystal and Sulli have the two beauty standards of Korea: Sulli looks innocent while Krystal looks cold. Then we have the Chinese queen of beauty and Luna who looks like a cool older sister. Amber always stand out with her pretty face and unique style. They are all talented: Amber can sing and rap well, Victoria is a great dancer and good singer, Krystal dances and sings amazingly, Sulli can sing and rap and, lastly, queen Luna who can be a main vocal and a main dancer in any other group. Their music is also unique and fun, their whole albums are dope, there is no filler. They have smart lyrics that talk about everything, including things girl groups don't usually talk about (listen to Milk, All Night and Toy, bye). They have cute songs (Chuu), summer songs (Hot Summer nomu dowo), powerful songs (Red Light), classy songs (4 Walls), fun songs (RPPP)... But still, they all are clearly F(x) songs, they all sound like F(x) like many shades of the same color. I'm so sad that SM simply let them go. It's such a waste. They deserved so much better. I love Sulli until I die and I'm really glad that she is given attention, but it's so unfair that she's the only one who we hear about. I'm a Revelup and I literally can't live without my queens, but it's so sad that SM had to neglect Fx after my daughters (ReVel) were born. I always defended SM for treating all of its artists well, when there was SNSD and F(x), both had yearly comebacks and both comebacks were great. But now it is fading a bit. It's regretful. I love them to death and I'll always be a MeU. And I'll never give up on SM, I know it'll always be the best.

Watching this again made me realized how sulli was truly one of the most beautiful and georgous faces in the k-industry of all times, miss her so much:(

Red Light was really ahead of its time. I remember being so mindblown from the moment the teaser photos were released with the half-half make up up to the relase of the music video! The taste really jumped out

레드라이트 컨셉은 전설이다....

f(x) seriously doesn’t have a bad song

The holy trinity of SM ggs: I got a boy , Red light and Zimzalabim

This song is like a funeral song to the gold era of kpop

I really love SM artists... SM stan. But hearing that 레드벨벳 (Red Velvet) will be having their fandom name faster/earlier than 에프엑스 f(x) IT'S VERY UNFAIR!!! ReasonS: F(x) is a senior of Red Velvet... Fans are waiting for 6 YEARS ... S.I.X Y.E.A.R.S ALREADY for f(x)'s fandom name F(x) really worked hard for SIX YEARS and still didn't get what they deserve F(x) already excel a lot F(x) won A LOT of awards (it's given prior to debut) F(x) proved already that they have that 'STAR' F(x) proved their 'TEAMWORK' F(x) proved that they CAN and specially because F(X) IS F(X) who WORK HARD, who STRUGGLES, who didn't get touched with their FAMILY because of WORK, who IMPROVED their talents and skills to PROVE that they are that girls but still didn't got the time to shine, to showcase and to be love by others. As a fan I hope that SM will consider F(x).... Because it hurts a lot to us (fans). PS. Still support f(x) and RV.... Don't make such fan wars #JusticeForFx #FairTreatmentPlease #SMPlease

*EVERYBODY MAKE SOME NOISE FOR THE BEST BADASS ANTHEM IN KPOP HISTORY* PERIODT WIGS SNATCHED :;;

This is the most aesthetic video i have never seen in kpop. I'm not a fan, but F(X) deserves better.

에프엑스 진짜 독보적 컨셉이라 .... 언니들 못잃어,,,, 25년에도 난 온다구 ,,,

F(x) are trendsetters. They basically invented the teen crush concept and brought an experimental sound to kpop. They stood out among other girl groups since they where targeted towards a more female audience during an era of kpop where most girl groups where marketed towards a male audience. Their discography are top notch, just listen to pink tape

Even sm couldn't make a video like this again

This song was way ahead of its time, to think it was released all the way back in 2014.

와 뮤비 비주얼 미쳤다 싶어서 혹시나 해서 찾아보니까 역시 민희진.... 와 진짜 시대를 이끌고 새 시대를 만들어 가는구나

the thing about f(x) songs is that it all ages like fine wine

F(x) nailed this concept. No group can pull a concept this well .so many groups are debuting each year but the amount of talent these ladies have is irreplaceable. This mv still gives goosebumps after so many years.f(5) forever. Proud of f(x) and proud to be a meu always💖💖💖💖💖👑👑👑👑👑

I swear the music video is better than alot music videos is 2020

F(x) will always be that best experimental group ever exist, easily own that title.. No doubt..

Literally one of the best comebacks in all of k-pop

no matter how much SM is going to not promote FX and always leave them underrated they are going always to be the greatest girl group they ever made and even after so many years SM wouldn't be able to replace FX or remake another FX

i hope aespa will cover this masterpiece specially since karina is a meu and its her fave song

Kep1er will be covering this song at KCON GERMANY 2024! Please, wait and see what happens. Thank you

This was one of the greatest comebacks and concepts ever! Y’all can’t tell me shit!

First time watching this... My life has changed.

If you don't *love f(x)* then you don't know what love is

다들 핑크테이프를 에펙 최고 명반으로 꼽지만 나한테는 이게 올타임 넘버원 앨범. 버릴곡 하나없고 멤버들 비주얼도 미쳤음.

This is one of the dopest pop songs I've ever heard! The chorus is so experimental and awesome, I've never heard anything like it. I follow maybe half a dozen K-Pop groups, but everything I've heard from f(x) has been so different and fresh. It frankly makes a lot of the other recent K-pop stuff I listen to kind of boring in comparison. Shame they seem to be in limbo at the moment, from what I hear.

I miss this era of Kpop, this is so unique and rare and the aesthetic is fire.

SM, please listen to us, their fans. f(x)’s concept is one of a kind. They changed the standards as to how a K-Pop girl group should look like. They have LOADS OF FANS all over the world, and that’s why they’re so talented and very unique. PLEASE BRING THEM BACK! They are one of the most influencias K-Pop groups. Believe me when I say that the industry is not the same without f(x) in the game.

F(x) 무대하는 거 보고싶다.. 이 곡으로 다시 나와줘ㅠㅠㅠㅠ 스타일링, 가사, 안무 다 취향이었던 레드라이트😢 못 들어본 노래인 척하고 또 좋아할게…

I became a MeU during the 4 Walls era and literally fall in love with all of them (even Sulli)... Now it's 2018 and I have been waiting my second comeback as a fan for a long time. I'M WAITING SM, MY GIRLS DESERVE MORE ATTENTION😩💔

literally the best kpop concept

I'm sad that f(x) logo is now not even included in the smtown live 2020 but I hope the best for our girls

Their music was so ahead of time thus they got minimal fame and always got overshadowed by snsd.

10 things I love about f(x): 1.They are unique, their comebacks are different everytime. 2.Luna's voice and personality. 3.Sulli's face. 4.Amber's style and her different everything. 5. JungLi cute moments. 6. Their talent, how they dance, move. 7.Krystal's face expressions. 8.Sulli's overcuteness and smile. 9.Victoria's body. 10. Them!

Literally no Kpop girl group has done a better dark concept as f(x) does it

This was their diss track for the government after the sewol incident. You guys can check the lyrics and rewatch the music video again for the hidden meanings.

희진언니가 만든 mv보러왔어요. 당시에도 진짜 센세이션해서 몇번이고 돌려봤는데 감각은 정말 남다른것 같아요. 진짜 잘만들었음!!!!

HEEEEEEY SM ENTERTAINMENT MAKE A COMEBACK TO F(x) #FXNEEDSCOMEBACK

Welcome to the MYs that just discovered this song through Next Level! Enjoy this gem from their seniors, the f(x) ladies.

지금 들어도 전혀 촌스럽지 않아..그립다..

The most badass kpop mv don’t fight me

Everyone's hair is so on point here 👌

idk but for me, when sm does experimental music it doesn't feel incoherent and cheap, rather it's revolutionary and sophisticated at the same time

FX 10년전인데 지금 봐도 넘 세련된 느낌..오히려 지금보다 더 좋은 느낌..

a few years ago f(x) wasn't a group i could connect to. Their kind of music just didn't suit my taste. But now i'm literally obsessed with all of their songs. I didn't know that the taste in music could change so drastically. ♥♥

I need f(x) comeback with this concept!

How smart SM is... the comeback of new girlgrup makes the senior SM's girlgroups are rising too because many people come to check the songs that give same vibe. 👏👏

I still think about this MV all the time, can't believe it's almost been a decade. Miss you Sulli!

I miss this concept and wish there were more group concepts like this

They were ahead of their time, their visuals and sound were just a masterpiece. I miss them so much.

FAVOURITE KPOP MV OMG

예술적인 감성 미침 다시보니 넘 좋다

Sulli look so different from here and now. She look like a true idol here but on her Instagram she's just a normal girl doing her own thing

I would love for f(x) to try a vampire concept

Answers to all comments: 1. Everyone is pretty 2. Amber is not a boy 3. Sulli will come back 4. We don't have a fandom name 5. Krystal is not a cold person, she's just an introvert 6. They don't have an official concert but they don't complain as much as you guys 7. No illuminati and bible burning 8. Please respect them and the music video.  Side note: I posted the above a year and a half ago so it's not really relevant anymore, let's update it. :) 1) Everyone is prettier than before 2) Amber is not a boy but now a grown woman 3) Sulli left the group :( but to us, f(x) will always be remembered as the iconic 5 4) We have a fandom name, MeU

This comeback is insane! The song is almost 10 years old and still sound SO fresh

Out of all SM artists, f(x) has the most beautiful mvs
