I know you guys are new to kpop but Teddy Park is a legendary producer! He also used to be an idol but originally from Los Angeles. He has his own label called Black label under Yg umbrella.
i don't know if you guys caught it in the documentary but the guy who sang "oppa gangnam style" used to be in the same agency, YG entertainment, as blackpink. you should def check out artists under their label they're all top notch :)
@@smt2400 yeah, but there is a difference. They are not a kpop band. They are a hip hop band. So they are the first KPOP ACT to play at Korea and Blackpink is the first KPOP BAND to perform at Korea. Proudly both these groups are under yg now. 😊

Jennie has 2 versions of SOLO. the first one was the original (2018) and the 2nd is the REMIX version. She performed it when they have a comeback last january 2021 at their THE SHOW online concert. She change the rap part at the remox version and wrote it by herself. But before watching the remix version, please watch first the original version. Thank youuuu
You guys can pick a fav and that's your bias, the one that you like the second best, that's your bias wrecker. Also, if you want more insight into their auditions and other things, they all have their own fanmade documentaries
Actually Jisoo don’t only speak Korean, she’s fluent in Japanese and she’s good in Chinese + she understands English very well she’s just not confident at speaking it (nowadays she’s talking more and more in English tho)
I mean why are you telling sometime that is not true jisoo isnt fluent in Japanese and she can't speak Chinese at all. Knowing one two words doesn't mean anything
@@Orgil0122 Not sure about Rose, but Jennie is definitely better than Jisoo. Their Japanese language is more than rudimentary as they were interviewed by two Japanese broadcasters in their studio, and everything were in Japanese.
The one fact that i like about u guys that you are really geniune with ur reaction.bcs you are actually enjoying learning and discovering about our Queens and you are paying attention to every detail. Just keep it up with that , we blinks support & appreciate ur comittement 💖
13:25 wasn't really Crazy over You but its Ready for Love it is an unreleased song but the real Crazy Over You was released already and its part of their 1st Full ALBUM "THE ALBUM" plsss check the whole album, its literally a no skip albummmm
I think u both need react to yg survival program. U will know how yg pick their artist. It's hard for the trainees. Only the best will be debut. One more thing for yg, their artist must have one thing that not many artist or idol have... That is swag. For me, until now, only artist from YG got that. For kpop I means.
"We do have a lot in here, but we're very particular on what we put out" The fandom needs to hear those, some people are getting mad because they only have 1 album 14 mvs ( I don't know if it's 14 but yeah) and i understand that, you don't need to be fed too much
tbh it didn't take 3yrs for BP to be successful. It took 0 days in Korea. As soon as they've debuted, they were the hottest rookie. Cause YG is one of the BIG 3 entertainments in here Korea. The fact that you've survived through all those training 'in YG'? Means now you're ready to be successful. Debute in YG literally makes everything happen. (Although it did take about 3 yrs for them to be successful worldwide too, not only in Asia.) Again, debute in YG is a guarantee of success in Asia not to mention Korea, but also in the States and Europe and everywhere else? I guess that was their ultimate goal but yet they didn't expect it this far.
For the last 5-6 years since they debuted , black pink has only 1 full album and few mini albums. Not many songs but every songs it’s hits!!! Made the fan want more and more sometime have to waiting for the comeback song for a year
UPDATE BLACKPINK WILL BE HEADLINING COACHELLA 2023 Coachella was the first US concert for them ever. It's not a standard venu, so people are not coming specifically for BlackPink. And Jisoo was very sick, her back was so bad it was hard for her to move. So add that to the Members not being sure how big the crowd would be, or if anyone would come to see them. They thought it might be a VERY small crowd(a few hundred). They didn't need to worry it was THE STAGE of the whole weekend at Coachella.
with any Kpop group.. they all train for years with skills they need but after they debut, there's no telling how much success and how far they will go. Most groups that don't make it big disband after a couple of years. So at the beginning when you said they "knew" that they were going to be this big and popular is really not true. The company trained these groups "hoping" that they will make it big. I think with BlackPink, it was a surprised like Teddy said that they made it this far and this big. I thinks its also because they have such unique members and music style that made them who they are.
Of course, those who only support one member are Lilies, Jensetters, Fansés, Sooyas and there is nothing wrong as long as they respect others and only focus in the member that they are supporting, because we cannot force them to be fans all members, that's why each member has their fanbase, and the others solo stans that start to fight or insult and hate, they are akgaes
LMAO bros... I died when y'all said "South Korea has a night life" then immediately followed up with "banh mi & pho". I'm dead. Those are Vietnamese foods. On another note: much appreciate the entertaining reaction vids! Keep it up.
thanks for reacting to their.. light up the sky netflix documentary!👍 pls react to their covers of "so hot" theblacklabel remix live performance, beyonce's "partition" dance cover and "sure thing" by miguel
Just wanna say that you are one of my fav reactors now. You both deserve hundreds and thousands to millions of subscribers. Keep it up ! PS : Thomas is freakin' awesome. Loce you Thomas ! 😘🤣❤
You can also react to "Blackpink Journey and Friendship". It is fanmade but have a lot of details about them as a group specifically their friendship and their journey throughout the years. You'll love it.
Oh! Thank you dude for including Philippines on your lists of favorite country, you guys are welcome here in the Philippines. The most friendly country. Hehee.
13:15 that song they recording not come out yet.. It's almost leaked 70%..maybe in next comeback They are the leaders. They work so hard and left everything for their dreaming and now they are one of the most successful artists in such a short time
Yes Thomas, you are warmly welcome here in Philippines! But it would be great if Shawn could tag along with you. Nice vid by the way..and hey, you guys could check out Blackpink ddu ddu ddu tokyo dome remix live its totally dope than coachella.
The line about roasting Lisa about being Thai is in reference to her liking "injeolmi". It's a traditional Korean dessert flavoring that's usually only in things older people order. Her trying to insist it's good to the other Korean girls that don't like it is funny/ironic.
They audition, Lisa for example had to beat thousands of girls on her audition, so yeah they have the talent… and on top of that they train for years to perfect their craft.
Blackpink was the first kpop girl group to perform at coachella. And the first kpop group was Epik High and at that time epik high used to be under YG ENT. of course the sensational Oppa Gangnam style by PSY used to be under YG
it took 0 years for BP to be famous. their debut songs charting and won so many awards right away. BP in 3 years was already SO BIG and no GG could do that in 3 years
YG entertainment doesn't produce idols they produce artists that's why everyone that came from them are superstars like Psy, BigMAMA, Bigbang, 2ne1, Winner,Ikon, AKMU and other solo artists like GUMMY, LeeHi, and se7en
Fun fact: Teddy Park once got request/ an offer to be the producer for Lady Gaga but he rejected the offer because he was busy preparing for 2ne1 comeback (one of YGE artists) at the time.
You guys are amazing!!! The most yt’ers just put it on their patreon because then they can make money (no hate) but don’t look at all their fans that made their channel “famous” and can’t afford patreon! Thanks, everyone appreciates it 🙏
YG himself came from Sao Taeji and friends who made Kpop today. Psy the singer of "Gangnam Style" is from YG. GD, the man who introduced hugh class fashion in Kpop, created different trends such as hairs, positions on groups and even brought lightstick into kpop is from YG. Then we have 2 legendary girl group, 2ne1 and Blackpink who made Kpop stronger and bigger.
l love most jisoo unnie means oldest she is so strong yg mistreated jisoo unnie, less lines, ignoring but now she is acting career started kdrama release December Disney hotstar
Gangnam style is a kpop song sang by PSY and during those Times PSY is under YG entertainment the same entertainment Teddy the producer was in when he’s still an idol before,2ne1, BIGBANG, and BLACKPINK. YG create legendary artist
Trivia the Founder of Yg entertainment (Yang Hyun Suk) was also and idol before and his group name was Seotaji and Boys and during those time they are like the most popular kpop group back then
I said it before under other reaction videos but I want to make you understand the whole kpop thing. Also, I don't want to sound rude or anything, these are things that I noticed over the years, since I first joined the fandom in 2014. K-pop is an _industry_ , not a genre or a scene (when you think of a scene, you think of punk or hip hop, which they are a like cultures, rather than a massification or what is mainstream - generally). It's often used as an umbrella term to describe the whole korean popular music (rock, r&b, hip hop and pop) but at the same time westeners think of kpop as merely idol music (Blackpink are idols) and idol groups usually mix many genre within a song, it's not just teen pop or bubblegum pop. The best way to describe the whole thing is that the music genres are from USA while the idol industry was born firstly in Japan and then, the formula spread. Japanese industry is different from the Korean one, but both are equally interesting imo. Quick side note: Japanese music contents are really hard to find on UA-cam, it's not like Japanese Animation that is heavily promoted in the West since the 70s (yes, Italy was one of the first few country to welcome Japanese Animation into their broadcasting!). On the other side we have Korea, and Korean agencies uses the "Motown formula" (Motown is still a label btw, but their golden era was in the 60s, with artists like The Supremes, the Jackson 5, The Temptations, Stevie Wonder and many others). This formula consited on being, as Motown Wikipedia page says, "fastidiously groomed [ *grooming as in make up and combing hair* ], dressed and choreographed for live performances". Motown Records trained their artists very very young and unexperienced in dance, acting, vocals, they way they should talk, how to behave on national TV and overall being visually appealing. Korea, furthermore, saw the chance to expand their market. Hope I didn't bore you, have a great day

Blackpink are the best girl group in the world
That's true
I'm pretty sure they're the biggest pop group in the world currently
a lot of truth
@@kmjc5214 i would disagree.. while they are definitely the biggest girl group in the world, there 100% are other groups that are bigger

Yes!
YG ent still owns a part of it i think as YHS also co produced and this song was released from YGE.
Yes!
Yeah JENNIE is a perfectionist ❤️ anything she do is perfect 💕
Fun fact: Psy, the "Gangam Style" dude, used to be signed under YG Entertainment. Now he runs his own entertainment company called P Nation.
They are THE FIRST KPOP GROUP to perform on coachella not only girl group. (sry my english)
Your English is good 👍🏼
And they really are an amazing group!
No, the 1st Kpop group perform in coachella is Epik High, Blackpink is the 1st GG, cmiiw
@@smt2400 Sorry I didn't know that

Teddy is very genius. I don't understand people still criticizing him.
It’s music it’s valid for criticism
Teddy is super! He is Blackpink member! In fact in the past, Teddy was also one of the popular boy group Korean artist.
Gangam Style is also produced by Teddy under the same company as Blackpink YG Entertainment.Gangam Style is Blackpink Senior
